If we enable our Forum module version 5.5.0/5.5.0a, it breaks the history on all accounts, the history section shows this error:

Error running count query for Account List: Query Failed SELECT count(*) c FROM threads INNER JOIN (select tst.team_set_id from team_sets_teams tst INNER JOIN team_memberships team_memberships ON tst.team_id = team_memberships.team_id AND team_memberships.user_id = '4316730e-7cb7-c81f-43b7-4bbce64dafff' AND team_memberships.deleted=0 group by tst.team_set_id) threads_tf on threads_tf.team_set_id = threads.team_set_id INNER JOIN accounts_threads ON (threads.id=accounts_threads.thread_id AND accounts_threads.account_id= 'd29e01e8-55a2-e759-71a1-4beafb0640fc') where ( accounts_threads.deleted=0 AND threads.deleted=0) AND threads.deleted=0 )::MySQL error 1054: Unknown column 'threads.team_set_id' in 'on clause'

HOWEVER, this error does NOT appear in google chrome, but only shows up in Internet Explorer and Firefox, so if we use chrome we're fine. Once I disable the addin, IE and FF work again, why would this work on Chrome but not any other browser?
