I, few days ago updated WHMCS to latest version. Payment Gateway configuration page not working from then. http://www.mydomain.com/billing/admi...iggateways.php return a white page with the text Module Not Activated only.
But my customers can pay without having any issue. I'm using 2checkout as my gateway.
I need your help.
