Topic: Unable to check group title collision
In admin_groups.php
$result = $db->query('SELECT 1 FROM '.$db->prefix.'groups WHERE g_title=\''.$db->escape($title).'\' && g_id!='.$_POST['group_id']) or error('Unable to check group title collision', __FILE__, __LINE__, $db->error());
I suggest replacing && with AND since && does not seem to work in postgres
