There are several causes of Internal Server Error. This troubleshooting tutorial is about the Internal Server Error that you get after upgrading plugins or activating one.

Here’s the simple step by step instructions:

  1. You will need access to your FTP or Cpanel.
  2. When accessing your WordPress website files, go to your site directory and locate the plugins folder, then rename it. Adding a single character is already enough to rename that folder and will cause all the plugins to be automatically deactivated. Then refresh your website.
  3. Once you get access again to your website, go ahead and re-edit the plugins folder and put it to its original name.
  4. Activate the plugins one by one until you get the internal server error with that plugin. Once you get the error, return to your directory and rename that folder of that particular plugin to deactivate it. Then refresh again your website so that you can get your live website back. Then go back again to that plugin folder in your directory and put back its original name again.
  5. You have the option now to either delete the plugin, or retain it as deactivated, or ask the plugin author for the bug solution.
