Web Development Software

Have you ever encountered the frustrating situation where you are unable to access the WordPress login page due to an HTTP error 500? Trust me, I understand your pain. As a web developer, I’ve come across this issue multiple times, and it can be quite a headache to troubleshoot. In this article, I’ll dive deep into the possible causes of this error and provide you with some insights and solutions to resolve it.

The HTTP Error 500

Before we delve into the specifics of the error, let’s first understand what the HTTP error 500 signifies. The HTTP error 500, also known as the Internal Server Error, is a generic error message that can occur for various reasons when trying to access a web page. It indicates that something has gone wrong on the server-side, preventing the page from loading correctly.

Possible Causes

Now, let’s explore some of the potential causes of the HTTP error 500 when trying to access the WordPress login page:

  1. Plugin or Theme Conflict: One common reason for encountering the HTTP error 500 is a conflict between plugins or themes installed on your WordPress site. If a recently activated plugin or theme is incompatible or poorly coded, it can trigger this error.
  2. Corrupted .htaccess File: The .htaccess file is an important configuration file in WordPress that controls various aspects of your site’s functionality. If this file becomes corrupted or contains incorrect code, it can lead to the HTTP error 500.
  3. Exhausted PHP Memory Limit: WordPress websites rely on PHP to function properly. If your site exceeds the allocated PHP memory limit, it can result in the HTTP error 500. This often happens when you have a large number of plugins or resource-intensive themes.
  4. Server Configuration Issues: Sometimes, the HTTP error 500 can be caused by server configuration problems. It could be due to misconfigured server settings, insufficient server resources, or other server-related issues.

Troubleshooting and Solutions

Now that we have identified some potential causes, let’s explore the troubleshooting steps and possible solutions to resolve the HTTP error 500:

  1. Disable Plugins and Themes: Start by deactivating all plugins and switching to a default WordPress theme. This will help you determine if the error is caused by a specific plugin or theme. If the error disappears, you can then reactivate each plugin/theme one by one to identify the culprit.
  2. Check the .htaccess File: Access your WordPress installation directory through FTP and locate the .htaccess file. Rename it to something like “htaccess_backup” and try accessing the login page again. If the error is resolved, you can generate a new .htaccess file by navigating to “Settings” -> “Permalinks” in your WordPress admin dashboard and clicking “Save Changes.”
  3. Increase PHP Memory Limit: If you suspect that the PHP memory limit is the cause, you can try increasing it by modifying the wp-config.php file. Add the following line of code just before the line that says “/* That’s all, stop editing! Happy publishing. */”:

define('WP_MEMORY_LIMIT', '256M');

Save the file and try accessing the login page again.

If none of the above solutions work, it’s advisable to reach out to your hosting provider for assistance. They will be able to investigate any server configuration issues and provide further guidance.


Encountering the HTTP error 500 when trying to access the WordPress login page can be frustrating. However, by following the troubleshooting steps outlined in this article, you should be able to identify and resolve the underlying cause of the error. Remember to always keep your plugins and themes up to date, and regularly backup your WordPress site to avoid any unexpected issues. Happy troubleshooting!
