In some cases, you might need to change the plugin folder name: for example, if you temporarily want to deactivate the plugin. Or, if you are beta testing the current GitHub version.
We recommend changing the folder name back to “really-simple-ssl” before you activate the plugin. The most important reason for this is that all of the deactivation methods (while retaining HTTPS) work correctly.
To rename the plugin folder, please go to a File Manager or FTP client, then navigate to the /wp-content/plugins/ directory. Make sure the Really Simple Security plugin is called “really-simple-ssl” (or really-simple-ssl-pro, if you are using the Pro version).
Then go to your Plugins overview on WordPress, and click “Activate” once more. You’re done!
