What do you mean? Are you saying when agents try to add collaborators the pop up does nothing when searching a name/email? That sounds like a few different things. Could be the search encountering a fatal error behind the scenes or could mean AJAX issues or could mean URL rewrite issues. We won’t know until you do some digging. Check all possible logs (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.) for any related errors.
Cheers.
