I went into the ftp directory and changed the name of the plugin file as below. I got an error message that said the plug file couldn’t be found. Then I changed it back to the correct name (without the – at the beginning). Then in WP-Admin I went to the Plugins and it said the plugin folder couldn’t be found and had been deactivated. I clicked to Activate it and it worked and no longer got the error message about it not being compatible. I created a new user and got the correct custom message.
I know deactivating it and reactivating it doesn’t work cause I tried that. I don’t know why renaming it, not being able to find it, then changing the name back, activating it and getting an error and then reactivating it again fixed it. But that worked for me.
