403 Forbidden, all the time, at every .onion page

Hello Tor Browser Team,

first of all I am new to this. So i get this Error "403 Fobidden - CSRF verfication failed" all the time.

I already looked it up and tried the things suggested there like : Clear cache, reinstall, try at other comupter etc etc. Still i get this Code everytime when i try to register at page, not visit a page.

Thx for any advice!
