I upgraded my forum to 2.1 today. TinyPortal on it, now I am getting a 404 error everytime after loggin in. After that all works fine, but when logging out and logging in same error again.
I see nothing in the logs.
When I uninstall TP the issue is gone. Reinstalled and it is back.
It seems to me that the redirect from logging in is somehow wrong. I tried both options: forum or Frontpage, but makes no difference
Forum is on https ….
Any ideas where to look ?
