Why does 504 Bad Gateway Timeout Error Occur? 

The 504 Bad Gateway Timeout Error is a standard issue that can occur on WordPress websites. This error occurs when something goes wrong on the server that is hosting your WordPress site. There are several possible causes of the 504 Bad Gateway Timeout Error, including:

  • Conflicts caused by plugins or themes: Incompatible plugins or themes may clash with other components of your website, resulting in the 504 error. This can occur when a plugin or theme is poorly coded or when it is not updated frequently.
  • Corrupted .htaccess File: Apache web servers use the .htaccess file as a configuration file to control website settings. This file may result in a 504 error if it is corrupted or has bad syntax.
  • Limitations on Server Resources: If your website consumes excessive amounts of CPU or RAM, the server may crash and return the 504 error.
  • Update to new version: Using an older version of WordPress might result in security flaws, compatibility problems, and other issues that can cause the 504 error.
  • PHP Errors: When there is a problem with the PHP code that is utilized to run your website, PHP errors may appear. A programming error or a problem with your server’s interoperability could be to blame for this.

Steps to Fix the 504 Bad Gateway Timeout Error
