Login Issue update
Ok, adding a few print statements in key places in the login php script tells me that the user query: $sql = "SELECT * FROM sys_user WHERE USERNAME = '$username'";
$user = $app->db->queryOneRecord($sql);
is returning a bool false value and not an array or object. I suspect this maybe a user access issue in the db? Any ideas? One thing I do know I changed was the hostname. Could this be the cause?
