Hi!

Just upgrated my system:

Here are the new specs:
OSTIcket. 1.12.4
PHP 7.3
MySQL 5.6.41-84.1
Apache 2.4.39

I migrated from 1.10.x. And now I'm receiving this email reporting DB Error #1064.

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'THEN A1.ticket_id END) AS q15, COUNT(DISTINCT CASE WHEN THEN A1.ticket_id' at line 1

I know this is an SQL error. Can anyone guide me in how to fix this problem? I don't understand the information reported.

Please let me know if I need to provide any other information!
Thanksful for any help!
