Common WordPress Errors and Admission Logs

HTTP response codes are returned by the server to indicate how a request was received. The first digit of the error code indicates the class of the mistake. For example; a 2xx response is a success response, a 3xx response is a redirect response, a 4xx indicates client fault, and a 5xx asking indicates a server error. Correctly identifying the response lawmaking an asset is returning may be crucial to a swift and piece of cake resolve.

Access Logs

Locating your site's access logs tin be helpful for diagnosing errors or traffic issues. Inside the logs you can locate the specific asking and the response or error code returned past the server. A search tin can be run for a timestamp, a URL or an IP address, or the logs can be filtered by type. Finally, logs can exist downloaded as a CSV for employ in external tools.

403 — Forbidden

The gist of the fault is uncomplicated – accessing the file or location (or the site itself) is forbidden past a directive on the site. There are a few means the request may be getting blocked:

File Permissions
- The folio you lot are attempting to access may accept the incorrect permissions. Reset default permissions with this guide.
File Type
- Sure files our server will not allow to be loaded in your browser, such every bit the .htaccess and wp-config.php files.
- Other files that cannot exist opened in your browser include files located in a directory that does not include an alphabetize.php file which allows those files to exist viewed.
Security Plugin
- Are you using a security plugin on your site? Disable plugins from the database without accessing the wp-admin dashboard.
.htaccess
- Cheque your site's .htaccess for rules preventing admission to the site, specifically any ALLOW or DENY rules.
- Upload a default .htaccess file.
Security Plugins
- Are you using a third-party firewall similar Sucuri or Cloudflare?
- Temporarily disabling the firewall tin confirm if it is causing the error.

404 — Not Found

This error means the nugget cannot exist plant. The showtime step to properly assess a 404 error is to determine which kind you are receiving: WordPress 404 or Nginx 404.

WordPress 404 Mistake

Notice that the WordPress theme is nonetheless loading. This fault usually shows when a page that can't be establish in the database is requested. Resolving this error is probable going to take place within WordPress.

If WordPress is throwing the 404 error:

Verify the page/post/WordPress element actually exists by locating it in your WordPress admin dashboard or the database
Verify the page/mail service/WordPress element is set equally public, published or otherwise in a visible land
Reset permalinks
Reset the .htaccess to default

Subsites in a new Multisite network:

Occasionally y'all may meet an issue with subdirectory multisite installations where subsites volition receive 404 errors on assets that should exist in the site's files.
For instance, you might run into 404s on assets like domain.com/subsite/wp-content/uploads/2019/ten/epitome.jpg
Your multisite may not have been created properly, reach out to Support for aid.

Nginx 404 Error

Notice this version shows the default Nginx 404 response folio instead. This is the folio that shows upwardly when a static file which doesn't exist is requested.

Nginx serves static assets, which is why a Nginx 404 specifically ways an issue with reading or locating the file at the path in your browser.

If Nginx is throwing the 404 fault:

Search the site's media directories for the file in question.
- If the file exists, it must be:
  - Located in the directory path matching the URL in your browser
  - Spelled the aforementioned in the browser and on the server
  - Using the aforementioned uppercase and lowercase characters, as static file names are case-sensitive
- If the file doesn't be:
  - The file needs to exist uploaded or relocated to the correct directory

NOTE: If y'all want to redirect all extraneous 404s to a custom error page, review our guide here.

405 — Method Not Immune

Dissimilar a 404 fault where the file isn't plant, a 405 error says the file is in that location but the method of request isn't immune. This error nearly commonly returned when your code is interacting incorrectly with WordPress functionality.

As this is near probable an upshot with WordPress code (such every bit a plugin or theme), follow along with our general troubleshooting guide.

429 — Also Many Requests

If y'all receive a 429 error information technology may exist apropos, but this is really a sign that our security system is working. This fault means you've exceeded the maximum number of requests to a page within the concluding second.

If yous receive this error in your browser when working, reach out to our Back up squad to investigate and remove the block if necessary.

Cases where the error is recurring will nearly probable be due to an automated process, so add a "sleep" or infinite out crons to resolve.

NOTE: To protect the integrity of our security organization, we cannot share the exact limit of requests per second that will generate this error.

444 — Connexion Closed Without A Response

A 444 is like to a 403, in that the request could be blocked by our server configuration. This differs from a 403 in that NGINX closes the connectedness without actually returning a FORBIDDEN response. In the browser this volition typically display a 502, but in WP Engine access logs information technology will bear witness a 444. The master stardom other than what is displayed to the visitor is that 444 condition codes are excluded from WP Engine'southward Billing calculations.

A 444 often ways that your site has an Nginx rule in identify to block traffic and that it is working.

If you're specifically receiving a 444 on a login page, this is likely due to a conflict with WP Engine'southward login protection security feature. In the browser you may encounter a 502 on the login page, however the logs will testify the 444 fault.

The solution is to modify the custom login page code to generate the login URL the same way that WordPress does. Hither'southward what WordPress uses in the wp-login.php file:

          <course proper noun="loginform" id="loginform" action="<?php echo esc_url( site_url( 'wp-login.php', 'login_post' ) ); ?>" method="post">

The most important role of the code from wp-login.php file is this portion:

          site_url( 'wp-login.php', 'login_post' )

Alternatively, when viewing the login page surround.wpengine.com/wp-login.php, nosotros expect the loginform action url to have a parameter wpe-login.

This parameter is added to this url via our mu-plugin. A filter is added, wpe_filter_site_url, which will add the wpe-login parameter to the URL string.

500 — Internal Server Error

A 500 error occurs when PHP cannot render properly. These errors are primarily acquired by 3 unlike issues:

PHP Fatal or PHP Syntax Error

- Review your Apache Error logs and look for timestamps around the time the error occurred for PHP fatal, syntax or parse.
- The mistake will signal to a file and a line number that should be reviewed by a programmer.
- If yous're unable to resolve the consequence, disabling the offending plugin or theme may resolve the mistake as well.

PHP Parse error: syntax error, unexpected T_STRING in /nas/wp/www/cluster-1234/somewebsite/wp-content/themes/rainbows/functions.php on line 4

In this error we can see there is a PHP parse error in the rainbows theme within the functions.php file on line four. Reviewing this file and line will be your next stride.

Bug with .htaccess

It's possible for the .htaccess to get corrupted over time. We e'er recommend using a default .htaccess, and never customizing it.
Follow our guide to replace your .htaccess with a default version.

Sectionalisation Mistake

Partitioning faults can be tricky to diagnose. The crusade of this error is a process trying to steal memory allocated to a different process, essentially bad or poorly implemented code.
If you would like to confirm if the mistake is a seg error, you can achieve out to our Back up squad to check the logs.
To resolve the consequence, disable plugins and change the theme one at a time.

502 — Bad Gateway

A 502 error refers to a cleaved connection (or "gateway") between two servers. At WP Engine, this commonly refers to the connection of NGINX and Apache. This is most normally caused by merely two things:

The request was killed by the Apache long process killer.
Apache is non there to render a response to NGINX.
- This can be bad code that Apache failed to process, or an event with the server itself.

Review our guide to diagnose and troubleshoot a 502 Bad Gateway.

503 — Service Unavailable

Unlike most other errors, a 503 is unfortunately much more vague. Typically, this is acquired by faulty code but it may also be caused by an overloaded server. In many cases information technology may simply resolve itself after a brief period of time.

Check your DNS
- A 503 mistake is not common on WP Engine, so we highly suggest verifying that your DNS is pointed to us properly. A 503 may indicate maintenance on other hosts.
- The 503 may be coming from an intermediate service also, such every bit a DNS-level firewall. Endeavour temporarily disabling whatever third-party firewalls.
Disable PHP scripts
- Follow along with our guide to disable all plugins and change your theme.
If the issue is nevertheless not resolved, accomplish out to our support team for boosted help.

504 — Gateway Timeout

A 504 mistake on WP Engine occurs for a very specific reason and due to this will only touch uncached requests. We use a circuitous queueing system to assistance ensure each site can serve the maximum number of requests quickly and equally adequately as possible. A 504 occurs when this queueing arrangement, and its excess are both total.

This fault helps identify one of the many things that makes WP Engine special. We do non charge you based on PHP workers or limit your available processing resources just because of what you tin can pay. Each website on a shared server has the same counterbalanced admission to a servers resources. Other hosts volition try to sell you PHP workers to get more coin from y'all, but we believe even the lowest priced hosting package deserves enterprise-grade performance.

In that location are systems in place to prevent 504s from occurring, only if y'all practise see these errors information technology may exist best to accomplish out to our Support direct for help resolving it.

If your site is not the culprit, we will follow up with the offender to resolve the issue. (Continue your Technical Contact upward to date!)

If your site is the culprit, we'll piece of work with y'all to identify the crusade of the traffic and suggest some possible solutions based on the cause:

Besides many uncached requests to the server
- Support tin review whatsoever cache-exclusions added to your site for bug. Some custom cache exclusions may need to be removed.
- Excess admin-ajax calls are a common culprit and can be identified in your access logs.
- Update or supervene upon offending plugins/themes. In some cases, you may demand to accomplish out to the Author of the asset.
- Piece of work with a developer to perform the same functions using buried methods.
Long running uncached requests
- Bank check your error logs for 502 errors, as these can identify killed processes and would indicate there are processes running likewise long and becoming backed upward, which in plow overburdens the request queue.
- Update or replace offending plugins/themes. In some cases, you may need to reach out to the Author of the asset.
- Optimize your database to help calls complete faster.
- Work with a developer to offload, optimize or interruption down the functionality then it completes more apace.
Upgrade
- If you lot've simply outgrown a shared environment and/or your traffic in the previous two ways cannot be improved, it may exist fourth dimension to upgrade to a dedicated hosting environment. A dedicated hosting environment ways that only your websites have access to a servers resources
- If you are already on a dedicated environment, it may be fourth dimension to motility to a larger server. A larger server will offer more resources for boosted growth and the traffic increases that brings.
- If you're experiencing increased traffic and 504s from a sale or seasonality, a temporary upgrade tin be considered equally well. We exercise not require annual purchases for dedicated servers.

520-530 — Cloudflare Fault Codes

If you're using Cloudflare, information technology'due south possible for their servers to create or intercept errors. This tin can dilute or otherwise confuse the meaning and make an issue more difficult to resolve.

All HTTP statuses between 520 and 530 are Cloudflare-specific codes with unique meanings.

Annotation: If you are troubleshooting GES, refer to this guide instead.

520 – A Catch-All "something went incorrect"

Request included more than 14KB of headers
Asking didn't include any headers at all
Empty response (444) from the origin server
Connection was reset after validating TCP handshake

521 – Blocked past Firewall

This should never happen on WP Engine servers considering we read the 10-Forwarded-For headers for all Cloudflare IP addresses.
521 ways the request was blocked by another firewall that wasn't WP Engine.

522 – Cloudflare IP Rate Express

At that place has been some kind of a connection reset later on the initial TCP handshake, or that the Cloudflare IP has been rate limited.
We do not charge per unit limit Cloudflare IPs, this error should not present itself due to WP Engine servers.

523 – Null-Routed Origin IP

This error only shows if the network path to the origin server is unavailable. This could happen if the origin servers IP is naught-routed.

524 – Timeout Betwixt Cloudflare and Origin

The almost common fault status from Cloudflare, as this is their long-process timeout.
Cloudflare will wait 100 seconds for a response from the origin server earlier invoking the timeout. WP Engine has a threescore 2d timeout on our own servers, then Cloudflare timeout isn't a mutual scenario.
This could be encountered on long requests like CSV imports, long running cron jobs, etc as these are subject to longer timeouts.

526 specifically means the origin server (WP Engine) does not have a valid certificate. 525 mostly means a more complex issue, similar a zero mismatch or lack of SNI.
This should not be an effect on WP Engine due to the nature of our encryption.

527 – Railgun-specific error

This error indicates a communication mistake or timeout mistake between the sender and listener services powering Railgun.
WP Engine does not support Railgun.

Mix of 52x errors

If you encounter 522/524/521 errors all mixed together, this typically indicates something is wrong at the origin. If there is actually an outcome with a Cloudflare edge node, the mistake bulletin volition indicate an issue with Cloudflare rather than the origin server.

"Are you sure you desire to do this? Please try again."

Most commonly this error comes from a plugin or theme event. To diagnose this you volition need to copy to a Staging/Development site and disable plugins and themes ane by one.

To right this issue y'all will need a functioning wp-config.php file with the correct database information. The easiest way to locate this is to refer to a backup.

Revert to a previous checkpoint, or download a checkpoint and restore the wp-config.php manually over SFTP.

If you continue to have issues, reach out to WP Engine Support to generate and sync new database credentials.

In that location are several variations to this error message; "WordPress failed to write to disk", "WordPress has failed to upload due to an fault failed to write file to disk", and "Unable to create directory wp-content/uploads/… Is its parent directory writable by the server?".

Each of these messages indicates that the file permissions are not correct and as such the file wasn't uploaded correctly.

Learn how to reset file permissions here.

If you've reset file permissions and are nevertheless having bug, confirm that the directory you lot're attempting to upload to exists and is accessible using SFTP. Effort changing to a dissimilar attainable directory.

XML Parsing Errors

These errors you lot will typically see when working with RSS feeds; "XML Parsing Error: XML or text declaration non at start of entity" or "Alarm: Cannot modify header information – headers already sent by …".

As this is a parse error, the issue will very probable exist within some PHP code. Did y'all modify a theme file recently? An extra space at the stop of a file or a tag not being closed are enough to crusade this error.
