PHP 8 Performance issues and Errors

Resolved
(@greencode)
I think you already know about this, looking at the previous support questions, but your plugin is currently unusable using PHP 8 and above. The error log just fills up and the backend is so slow.
Any idea when this will be fixed or should I look around for another plugin?

The developer’s solution (after using their ticketing system) is to direct you to download a fixed version of the plugin, only available via a uniquely generated off-site (not hosted by ww.wp.xz.cn) link

So until they get around to fixing the version hosted on ww.wp.xz.cn

You can suppress this error by replacing line 287 in /lib/exception/handler.php

Replace this:
return error_log( $message, 0 );

With:
return true;
