Could I ask how you have your admin directory set up? Have you by any chance changed the init.php file to do this? If so, this may well be what is causing your issue. Please could you clarify that first of all? If you have any issues going forward on these, please do let us know before you continue so that we can take a look.
We have simply moved where we do support. We are still here (Hi! 🙂 ) dont worry. This forum is now fully staffed, and if anything does need to be escalated we can get it to a ticket from here and get it to our devs. We can access your details are normal too. Its simply a change in how we issue support, not a removal of support
