… it’s not possible to activate the “Remember me”-checkbox on the logon screen.
Cookies don’t seem to work properly either, I can’t “view posts since last visit” anymore :roll:
We are aware of the issue and are working on a solution.
In the meantime you may consider to use a browser convenience feature to store your login.
Sorry for the inconvenience.
I also receive “general error” almost everywhere, it is almost impossible to navigate 
Thanks for providing additional details offline. Your issues should be resolved by now. We have introduced a Single Sign-On solution 2 weeks ago and we have still to resolve some minor issues due to the performed changes.
