DB function failed with error number 1054 Unknown column 'aro.aro_id' in 'on clause' SQL=SELECT a.*, [login to view URL] AS groupname FROM jos_users AS a INNER JOIN jos_core_acl_aro AS aro ON [login to view URL] = [login to view URL] INNER JOIN jos_core_acl_groups_aro_map AS gm ON gm.aro_id = aro.aro_id INNER JOIN jos_core_acl_aro_groups AS g ON g.group_id = gm.group_id GROUP BY [login to view URL] LIMIT 0, 50 we need that fixed and the mobile Joomla plugin that is already installed properly configured
