Beryl 3.211 Advanced openWRT cannot log in

Hi,

currently my Beryl is on 3.211 stable.
I installed openWRT in Advanced, but I cannot log in.
Everytime I try to log in, I get redirected to the login page.
I also get no message if I enter a wrong password.

The advanced page password is your root password, the one you use to ssh to the router.

Well, I am using the only password that I have for this router. I can ssh in with that but cannot log in to openWRT

There there must be something wrong with luci.

I think I tried before on 3.211 and it should work without problem.
