XF 1.5 Field 'ch_msg_color' doesn't have a default value

[Triops]

Where does this field come frome please?
Suddenly I get this error with every try for registration.
I deactivated some addons before but am unsure, if this is related (Crispins user map and few others, but reactivated user map again - this didn't solve the problem).
