Why do I get:

Database error in vBulletin 3.8.1:

Invalid SQL:

SELECT usergroup.usergroupid, usergroup.title, usergroup.isstaff
COUNT(user.userid) AS membercount
FROM usergroup AS usergroup
LEFT JOIN user AS user ON (user.usergroupid = usergroup.usergroupid OR FIND_IN_SET(usergroup.usergroupid, user.membergroupids))
WHERE usergroup.isstaff = '1'
GROUP BY usergroup.usergroupid
ORDER BY usergroup.title ASC;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'COUNT(user.userid) AS membercount
FROM usergroup AS usergroup
LEFT JOIN user AS ' at line 2
Error Number : 1064

?

Heck, can't even uninstall this:

Database error in vBulletin 3.8.1:

Invalid SQL:
ALTER TABLE usergroup DROP staff;

MySQL Error : Can't DROP 'staff'; check that column/key exists
