Was truing up a software subscription list and had removed licenses. Tapping the save button at the bottom of the screen popped the following in apache2 / error . log
[Wed Mar 05 14:41:13.095698 2025] [php:error] [pid 627406:tid 627406] [client w.x.y.z:53676] PHP Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'WHERE software_id = 39' at line 1 in /var/www/html/post/user/software.php:132\nStack trace:\n#0 /var/www/html/post/user/software.php(132): mysqli_query()\n#1 /var/www/html/post.php(49): require_once('...')\n#2 {main}\n thrown in /var/www/html/post/user/software.php on line 132, referer: https://itflow.server.domain/software.php?client_id=4
I was able to go into client / contacts and remove the licenses individually.
