I am having a similar error. If I select all selected members on this page everything works great. But if I select All Members in search I get the following.
"Control panel message
SELECT t1.USER_ID,t4.GROUP_ID FROM ubbt_USERS as t1, ubbt_USER_GROUPS as t4 WHERE t1.USER_ID <> '1' and t1.USER_ID = t4.USER_ID and t2.USER_TOTAL_POSTS > '100' GROUP BY USER_ID ORDER BY USER_ID ASC
Unknown table 't2' in where clause"
