What is the 500 internal server error?

The web definitions of the 500 internal server error is vague.

How to resolve 500 internal server error? 

Here’s are a few alternatives you can follow to resolve this notorious 500 internal server error:

1. Turn on debugging

Whenever your WordPress site throws you a white screen or a server error, we recommend you to turn your debugging on. You can turn debugging on by editing your site’s wp-config.php file. Once you’ve accessed this file, search for WP_DEBUG within. Set it to “true”. If you don’t see it in there, you’ll need to create it yourself. You should have a line that looks like this: 

define( "WP_DEBUG", true );

Safe it and reload your site to see if anything has changed. The server error may disappear and might be replaced with a different error that tells you where the issue is exactly. 

Even if turning on debugging doesn’t give you the result, it is a good idea to leave it turned on until the issue is resolved.

2. Deactivate all plugins and switch themes

Try to deactivate all your plugins and see what’s what. If your website loads without the server error the issue possibly was with one of your plugins. You can switch them on one-by-one to figure out which one caused this error. Alternatively, you can also switch your theme to a default. If the site loads without 500 internal server error, the issue was within the theme. You can reach us by opening a support ticket so that our support team agents can assist you further. Majorily, these errors are actually caused by plugins. 

3. Check your .htaccess file

The .htaccess file contains a number of rules that tell the server what to do in certain cases. It is commonly used for rewriting URLs or preventing access to your site for malicious intent. Use your FTP editor and check if you have an .htaccess file in your WordPress root folder. You may need to make sure your FTP editor lists hidden files before you do this. Make a backup and then delete the whole file. This may remove some important rules, but if the internal server error was caused by a mistake within the file, this will tell you.

So if the error is now resolved, the issue was with the .htaccess file. Try restoring the file and then deleting blocks of it. And if at some point, the site starts functioning, you know which block the issue is in. You can then narrow it down to a single line and then remove that line or ask us for further assistance.

4. Increase your memory

Increasing your memory limit should help in resolving this error. To do this, open your wp-config.php file in the WordPress root directory and search for WP_MEMORY_LIMIT. Change the value to something like “64M”. If it doesn’t, paste the following line into the file:

define('WP_MEMORY_LIMIT', '64M');

If your host has monitoring available, take a look at your resource usage with various plugins on and off to get a better idea of what is wasting those precious megabytes in your WordPress site.

5. Ask your host

There might be a few uncommon issues which can lead to 500 internal server errors in WordPress, but at this point it may be best to ask your host. Probably, the issue could be a genuine server issue, which your host can at least confirm and he can also look at things like file permissions and other sources.

6. Reinstall your WordPress theme

While we do not suggest this as a better option and since this doesn’t help in most cases, but there are some edge cases where a reinstall of WordPress theme could fix the issue. But if you wish to do this, we recommend following the manual WordPress theme instructions in the WordPress Codex.
