XF 2.2 Unable to create node, error = Field 'z61_character_min_enable' doesn't have a default value


Well-known member
Trying to create a new (child) forum node, and get the following error, with the node not being created.
Retried with all addons disabled, same result/error.

Oops! We ran into some problems.

Core issue, or the result of an addon changing the DB?
