The error on my Android device is:
"SQL error {mysqli}Uknown Column "
g.group_max_recipients" in 'field list' [1054] A SQL error occurred while fetching this page.
From the Tapatalk support forum:
Current
phpbb plugin is fully tested on 3.0.3 and later. Problem like missing field 'group_max_recipients' will only happen on forum system lower than 3.0.3.
However you can just remove below code in file mobiquo/function/create_message.php to see if it works:
// Get maximum number of allowed recipients
$sql = 'SELECT MAX(g.group_max_recipients) as max_recipients
FROM ' . GROUPS_TABLE . ' g, ' . USER_GROUP_TABLE . ' ug
WHERE ug.user_id = ' . $user->data['user_id'] . '
AND ug.user_pending = 0
AND ug.group_id = g.group_id';
$result = $db->sql_query($sql);
$max_recipients = (int) $db->sql_fetchfield('max_recipients');
$db->sql_freeresult($result);
http://www.tapatalk.com/forum/showthread.php?t=5380.. Looks like the solution is either to try modifying the configuration file as indicated above OR upgrading the phpbb version this board runs on to a more current version. I'm not sure if this would be possible for anyone but the top level board administrator with root access to the server(s) the forum is running on currently.
