 * Hello,
 * I saw posts about backup errors with PHP 8.0. I do not have this problem but 
   something else.
 * My sites with PHP 8.0 are showing some “PHP Deprecated” notice in the error_log
   file.
 *     ```
       [13-Apr-2022 07:19:24 UTC] PHP Deprecated:  usort(): Returning bool from comparison function is deprecated, return an integer less than, equal to, or greater than zero in /wp-content/plugins/worker/src/MMB/Stats.php on line 123
       ```

 * Hey there,
 * Filip here at the other end.
 * We did have some users reporting similar issues, it was due to the incompatibility
   with PHP 8.0 and our Worker plugin. Hopefully, with the new Worker plugin update,
   everything should be A-Okay.
 * Let me know if you have any questions.
 * Kind regards,
