I get this error

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1364 - Field 'description' doesn't have a default value
Query:
INSERT INTO mybb_settinggroups (`name`,`title`,`disporder`,`isdefault`) VALUES ('lock','Lock Settings',1,0)

Why?

Looks like you're either missing a "description" field or the "description" has no specific value.
Insert it within the query and see if it's fixed, or insert something into the description value.
