MyBB Community Forums

When I try to move a thread to someplace else, the following message shows in my browser as soon as I set where I want to move the thread to.

MySQL error: 1066
Not unique table/alias: 's'
Query: DELETE s FROM (mybb_favorites s, mybb_users u) WHERE s.type='s' AND s.tid IN (1) AND s.uid=u.uid AND (u.usergroup IN (1,2,5,1,2,5) OR CONCAT(',',u.additionalgroups,',') LIKE ',1,' OR CONCAT(',',u.additionalgroups,',') LIKE ',2,' OR CONCAT(',',u.additionalgroups,',') LIKE ',5,' OR CONCAT(',',u.additionalgroups,',') LIKE ',1,' OR CONCAT(',',u.additionalgroups,',') LIKE ',2,' OR CONCAT(',',u.additionalgroups,',') LIKE ',5,')

I have to go back to the forum then manually, but the thread is moved. Still wonder why I get this Error. My MySQL knowledge is not good enough and I hope someone could help me.
