I've updated to the latest PBAS update (4.5-55). When I now "Login in to CP" as a customer they can no longer manage the subscriptions. They can use the rest of the PBAS Control panel, just not the link/redirect into the control panel for a subscription. The system is running PBAS, PPA, and two plesk panel servers (one each of linux and windows). All are patched to the latest levels. As far as I can tell this affects them all, whether windows or linux. Is there a know issue? Is there something I should be switching on? We don't yet have full SSL as the system is not yet in production.
