Might be redirecting here, try this:
Find:
Code:
$to_url = (!empty($active_modules["Simple_Mode"]) || $login_type == "A" ? $xcart_catalogs["admin"] : $xcart_catalogs["provider"])."/home.php";
Change to:
Code:
$to_url = (!empty($active_modules["Simple_Mode"]) || $login_type == "A" ? $xcart_catalogs["admin"] : $xcart_catalogs["provider"])."/orders.php";
