Yesterday, our system was running fine—I responded to a number of tickets, and pasted and/or attached images. Today, when I try the same, I get this:
I did not change any settings on our ticket system. Whether I paste or attach via the button, I get the same error. I am far from a SQL expert, but I can make my way around it if necessary to edit/fix a table, but I don't have any idea where to start.
There are no relevant entries in the system log. I am totally lost, and would appreciate any help. We are running version v1.15.3.1 (65ca4e6) on Apache using MySQL 10.2.41 and PHP 7.3.33.
