This error can be frustrating, as it prevents you from accessing your website and may cause your visitors to experience the same issue.

Here are the steps on how to solve HTTP error 500 in WordPress:

Check for plugin or theme conflicts

One of the most common causes of HTTP error 500 in WordPress is plugin or theme conflicts. If you recently installed a new plugin or theme, try disabling it and see if the issue is resolved. If the issue is resolved, you may need to find an alternative plugin or theme.

Increase the PHP memory limit

Another common cause of HTTP error 500 is a low PHP memory limit. To increase the PHP memory limit, you will need to edit your website’s wp-config.php file. Simply add the following code to the file

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

Check for syntax errors

If you recently made changes to your website’s code, make sure to check for syntax errors. Even a small syntax error can cause HTTP error 500. Use a code editor to check for syntax errors, or revert back to a previous version of your website’s code.

Check for server issues

If the above steps do not resolve the issue, it may be a server issue. Contact your web hosting provider to check if there are any server issues causing HTTP error 500. They may be able to resolve the issue on their end.

Things To Consider When Solving HTTP Error 500

Here are some additional points to consider when trying to solve HTTP error 500 in WordPress:

Check server logs: Your web hosting provider may have server logs that can help diagnose the issue causing HTTP error 500. Ask your provider to review the logs to see if there are any server-side issues causing the error.

Deactivate all plugins: If you are unable to identify which plugin is causing the issue, try deactivating all plugins and then activating them one by one to see which one is causing the issue.

Reinstall WordPress core files: If the issue is caused by corrupted WordPress core files, try reinstalling them. This can be done by downloading the latest version of WordPress and replacing the core files via FTP.

Check file permissions: Make sure that the file permissions of your website’s files and folders are set correctly. Incorrect file permissions can cause HTTP error 500.

Use a caching plugin: Using a caching plugin can help improve your website’s performance and reduce the likelihood of HTTP error 500. Popular caching plugins for WordPress include WP Super Cache and W3 Total Cache.

By considering these additional points, you can further troubleshoot and resolve HTTP error 500 in WordPress. Remember to always backup your website before making any changes, and seek assistance from a professional if you are unsure of what to do.
