Here are 10 different causes and solutions to fix WordPress 500 Internal Server Error:
IMPORTANT: Before proceeding with this tutorial, we recommend making a backup of your site to prevent any file loss during the changes.
In most cases, WordPress HTTP error 500 occurs because of a new plugin. If your page experiences issues after a new installation or update, then you can easily fix it by deactivating or removing the plugin.
There are two easy ways of doing this: through the WordPress dashboard or File Manager.
If you are still able to access WordPress from your hpanel, do so, and select Plugins.
If you don’t have access to your dashboard, you can also disable or remove plugins through File Manager on your hosting control panel. Here we’re using Hostinger’s hPanel as an example:
In case the problem persists, repeat the process until all plugins are deactivated or until your website is working again. Once you find out which plugin caused the 500 error, remove it completely, and either reinstall it or try to find a substitute that performs the same.
A new theme or update is another common cause of this error. To fix it, simply change the existing theme to a new one or change it to one of the default options.
If you can access the WordPress admin area, try to change the WordPress theme.
Alternatively, you can also change themes by editing the MySQL database via phpMyAdmin in the control panel. Here’s how to do it with the hPanel:
Now, reload your site with the new theme and see if it fixed the issue.
To see a list of installed themes on your database that can be used to change the existing one, go to the wp-content/themes directory using File Manager.
Another way to get rid of the error 500 is to check your current .htaccess file and make sure that it’s not corrupted. However, you can also just create a completely new one. Here’s what you need to do:
A memory limit or insufficient PHP value can be another reason behind the issue in WordPress, as scripts and plugins require a certain amount of memory to work.
To fix the memory limit, increase the PHP limit by editing the .htaccess file manually. Here are the lines that we recommend adding:
php_value upload_max_filesize 128M php_value post_max_size 128M php_value max_execution_time 300 php_value max_input_time 300 php_value memory_limit 256M
Once done, refresh your website. If the issue is related to insufficient PHP values, this solution will fix the error.
Some plugins and scripts require a specific PHP version to work properly. If the requirements are not met, the 500 Internal Server Error may appear.
To change the PHP version via the hPanel, simply log in and head to the PHP configurations under the Advanced tab.
In case you don’t know what PHP version is needed, try upgrading or downgrading. Don’t forget to save the settings and refresh your website after each change.
If it still doesn’t fix the issue, change your PHP version to the initial one (which was used at the beginning) and proceed to the next option.
Finding the reason for the WordPress 500 Internal Server Error is arguably the toughest part of fixing it. If none of the options above helped you, you may need to investigate deeper by enabling an error display that allows you to find and locate a specific issue on your site.
You can easily do so through the PHP Configuration section on your hosting control panel. Switch to the PHP Options and put a check on the display_errors and log_errors columns, then scroll down and Save. Once you refresh your site, it should display the specific.
Alternatively, you can also create a separate error log file and generate entries through the .htaccess file.
If the step above didn’t work to fix the error in WordPress, it has its own special debugging system that you can use to troubleshoot issues. You can use it to generate an error log in the wp_content folder or to display the error 500 on your site when you access it. All you need to do is to enable the wp_debug feature.
In case you’ve backed up WordPress when it was functional, restoring the backup is also an option. All you need to do is remove all your recent site files, and re-upload the backup to your site. You can also restore your site with a database backup.
However, if you are not a fan of restoring WordPress backups manually, you can use a plugin. It won’t be much help if your site is not functional, of course, but it can surely help avoid similar issues in the future.
To create and restore a backup through the All-in-One WP Migration plugin, follow these steps:
If nothing seems to go right, there is a more extreme option to fix the 500 error. You will be replacing all of the core WordPress files. Here’s how:
Note: make sure that you already have a backup of your current website in case anything goes wrong.
If at the end of the day all the methods haven’t been successful and you still can’t solve the issue of the 500 error, then it’s time for some more help. Contact your web hosting customer success team and get some backup.
They will be able to check the server logs and locate the root cause of your issue.
The most common reasons behind the Internal Server Error are corrupted .htaccess files, a new theme and or plugin, incompatible PHP version, or a WordPress update.
One of the best things to do when troubleshooting this error is to trace back your steps. Try remembering what specific event caused your site to stop functioning. When you know exactly what went wrong, find the best solution from the list.
Since there are different web servers, browsers, and operating systems, the 500 internal server error can appear in a handful of ways. Here are a few variations that you’ll see:
