 * Hi. My website crashed when upgrading to PHP 8.4 due to problems with my WordPress
   plugins. I am trying to identify the problem and found a critical error in your
   Comment Link Remove Plugin for WordPress. Can you please confirm whether you 
   can fix this? I ran a scan of your code and also identified 2 warnings for you
   below:
 * #!/usr/bin/env php
 * FILE: …/wp-content/plugins/comment-link-remove/qc-support-promo-page/qc-clr-recommendbot-
   support-plugin.php
 * FOUND **1 ERROR** AFFECTING 1 LINE
 * 276 | ERROR | “**$this**” can no longer be used in a plain function or method
   since PHP 7.1.
 * FILE: …/wp-content/plugins/comment-link-remove/qc-clr-email-subscription.php 
   FOUND 0 ERRORS AND 2 WARNINGS AFFECTING 1 LINE
 * 34 | WARNING | Using ${var} in strings is deprecated since PHP 8.2, use {$var}
   instead. Found: ${offset} 34 | WARNING | Using ${var} in strings is deprecated
   since PHP 8.2, use {$var} instead. Found: ${items_per_page}
