65+ of the Most Common WordPress Errors and How to Fix Them

In order to cover so many different issues in a single post, I’ve organized them roughly according to type. Below you’ll find a general description of the various components of your WordPress site and the problems they might experience, followed by the specific errors and their solutions.

400 Errors

Errors labeled with a number between 400 and 499 are HTTP client errors. This usually means that something has gone wrong during the communication between the browser your site’s visitor is using and your site’s server.

1. 400 Bad Request

The 400 Bad Request response is a catch-all for when your server experiences a client error, but it doesn’t fall into a specific category. That means this error has several possible causes, including:

  • An incorrectly-typed URL or one that contains disallowed characters.
  • Corrupted browser caches or cookies.
  • Discrepancies between Domain Name System (DNS) data and your local DNS cache.
  • Trying to upload a file that is too large.
  • Some kind of general server error.

Potential solutions include checking the URL for typos, clearing your browser cache and cookies, clearing your DNS cache, and deactivating browser extensions.

2. 403 Forbidden

There are many measures in place to keep your WordPress site safe, including varying levels of ‘permissions’. While this feature can prevent people who shouldn’t have access to your site from gaining entry, it can sometimes cause problems if the permissions are not set properly.

A 403 Forbidden error is one such problem:
