PHP 8 compatability?

Hi – had to deactivate this plugin when our server was upgraded to PHP 8.0.

Got the following error in the log. (Redacted)

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught TypeError: implode(): Argument #2 ($array) must be of type ?array, string given in ****/wp-content/plugins/prdctfltr/lib/pf-frontend.php:3242

Please let me know when you have upgraded the plugin to support PHP 8.1.
