I could suggest a few things:

  • Try enabling debug mode to see if there are any more errors that could lead you to the right direction. You can do that by setting WP DEBUG to true in your wp-config.php.

  • Check your PHP error log for some more information too.

  • As this is working for you on another server, I would recommend checking the following:

    • Make sure that the PHP version is the same
    • Make sure that the MySQL version is also the same
    • Make sure that there are no PHP settings present on the working server that have not been carried over to the new one. You can check that in the php.ini file.
    • Make sure that you have all of the PHP modules enabled. You can check that by creating a PHP info file with the following code:


Alternatively, it might be a good idea to open this as an issue on the official GitHub page of the plugin.

Let me know how it goes. Regards, Bobby
