Double Post Merger Support

[Volux]

I downloaded the Auto Post Merger mod and when I activate it. I get this error:

MyBB has experienced an internal SQL error and cannot continue.

SQL Error:
1146 - Table 'adminvel_avmybb.mybb_mybb_settinggroups' doesn't exist
Query:
DELETE FROM mybb_mybb_settinggroups WHERE name = 'doublepostplugin'
