       I already downloaded the plugin from GitHub, deleted the plugin and installed that version. 
   
       Same results.
   
       I am using php version 7.4.1

 * You’ll need to contact whoever does support for your web hosting and ask them
   to enable the PHP ‘ctype’ extension. It’s supposed to be installed and enabled
   by default. In your case, it isn’t and thus the issue.
 * Good luck!
