Tables without primary keys

[dragonexpert]

I can confirm that adding an auto increment primary key to the mybb_adminlog table causes no issues. I did that a while back because when I am trying to write custom admin log entries, it can be helpful to be able to click the edit row so you can view all serialized data.

Yep, confirming this worked for me too. (adding the auto increment myself, manually)

Thanks all for the speedy assistance!
