Hi, i got a ts-509 this box has worked as a charm until i resently had a power outage and had to change disks. Now it do work again but suddenly i cant log in to it on the web page to manage apps etc. it works until the point where i press the login button then nothing happens, anyone got any idea what this problem can be?

Everything els works as it shoud, i can download to it and connect to it with the qfinder and phone apps but not trough the admin page
