I noticed recently under my Drupal "recent logged messages", I've been getting errors logged with the message:
"Deprecated function, use CRM_Core_PseudoConstant::getKey Array ( [civi.tag] => deprecated )"
Error:  operator not supported for strings in CRM_Utils_Recent::del() (line 173 of C:\xampp\htdocs\sites\all\modules\civicrm\CRM\Utils\Recent.php).
What does this mean? I am on Drupal 7 and CiviCRM 4.7.22. I think this seems to appear when I'm trying to delete a case or delete any activities. I see the spinner keep running forever and just hangs.
