Hi again, @Simon,
I really appreciate your friendly, postive attitde and enthusiam.
And thank you for reporting back that the issue appears to be resolved after upgrading to the latest version of osTicket Awesome.
I still have to caution you, however: osTicket does not yet support PHP 7.4. If you run 7.4 you may run into all sorts of weird issues.
I highly recommend that you switch to PHP 7.3!
