Create Website Backup

Before you experiment with your website, it’s always smart to take a complete backup of your website.

To take a comprehensive backup, you have to save copies of WordPress files as well as your databases.

You can take backup of your either through WordPress backup plugins or manually backup your site via FTP. Here’s how you can manually backup the WordPress website.

Try Reloading the Page

In a few cases, the 500 internal error clears up by itself within a few minutes. For instance, if you’ve simply made modifications to a plugin or theme, or your web host is facing an odd surge in traffic, you may see a server error. If this is true in your case, a simple reload can get things back to normal.

To refresh the page, you can press ‘F5’ (command + R if on Mac)for simple refresh and ‘Ctrl + Shift + R’ for a hard refresh.

Clear Your Browser Cache

Another fix for this error is to clear your browser cache. The cache of your browser likely got corrupted. So, it’s causing issues while trying to access websites.

Chrome, Brave, Opera, Vivaldi

To clear your cache, you need to press Ctrl + Shift + Delete. Alternatively, you can click the three vertical dots in the top-right corner then go to More tools> Clear browsing data.

Clear Cache

Ensure that you have checked the Cached Images and files box. Then click on the Clear data button.

Clear browser’s cache by pressing the Ctrl + Shift + Delete keyboard shortcut. By doing so, it will open the Clear Recent History window. In the Time range to clear drop-down menu, select Everything. Check the Cache box, and then click on OK.

Access Your Error Logs

Your website’s error logs may offer insight into what’s causing the 500 error. Depending on your host these logs may be cycled quite often, so you will need to have a look as soon as possible.

You can check out the error logs by accessing the website’s files through SFTP and search for the /logs directory. Then, select the website that’s encountering the error. You can see several directories at this point. You’ll need to check the one with the most recent date.

You can always view the log by downloading it and opening it with your preferred text editor. Expectedly, your error logs will give you some additional information for this 500 error.

Another option is to enable the WordPress debug log. You can do so by connecting to your site via SFTP and opening your wp-config.php file. Inside it, look for the following line:

define('WP_DEBUG', false);

Once you find it, replace it with the following:

define( 'WP_DEBUG', true );

define( 'WP_DEBUG_DISPLAY', false );

define( 'WP_DEBUG_LOG', true );

This will create a debug.log file, which you can find under the /wp-content/ directory. Just be sure to change the WP_DEBUG value back to “false” when you’re done troubleshooting.

Check For Problems With Your .htaccess File

Your .htaccess file is one of the core WordPress files. It consists of several rules for your server. Hence, there is a possibility that it could be one of the causes for a 500 Internal Server Error.

In case your .htaccess file has become corrupted, you will have to create a new one. Begin the process by logging into your website through an SFTP and look for the .htaccess file. On finding the file, rename it to .htaccess_old.

Renaming .htaccess

Now, let’s create a new .htaccess file in your text editor and paste the following:

# BEGIN WordPress

RewriteEngine On

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

RewriteBase /

RewriteRule ^index.php$ - [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

# END WordPress

Next, upload the newly created .htaccess file. Then refresh your website in your browser and check whether the error message is still showing or not.

Ask Your Host About Potential Server Issues

If every other method you try to fix 500 Internal Server Error fails, then it may be a server issue. This could only be confirmed by the web host.
