Encountered this whilst attempting to upgrade phpBB using svn:
SQL ERROR [ mysql4 ] Unknown column 'g.group_skip_auth' in 'where clause' [1054] SQL SELECT a.forum_id, a.auth_option_id, a.auth_role_id, a.auth_setting FROM acl_groups a, user_group ug, groups g WHERE a.group_id = ug.group_idAND g.group_id = ug.group_id AND ug.user_pending = 0 AND NOT (ug.group_leader = 1 AND g.group_skip_auth = 1) AND ug.user_id = 22 BACKTRACE
The solution took awhile to determine but it’s quite simple. Go to your board’s database update module at:
http://example.com/install/database_update.php
which will add the requisite columns to the tables.
