MySQL Version 5.5.41-MariaDB-log - MariaDB Server
PHP Version 7.4.6
After a fresh installation of osTicket 1.15.4 an agent can't delete Notes he made himself by a User.
Agent Panel -> Users -> 'select user' -> Notes
As an agent you can make new notes and edit notes by clicking the icons and fill in the textfield.
Clicking the bin icon gives a waring 'Confirm Deletion' and by clicking 'OK' the notes are still there.
You can't delete them.
I already had this error in the earlier versions of osTicket.
Does someone else has the same error?
How can I fix this.
