This doesn't seem to be the problem... Sure it could be an error with the php environment but I changed everything as posted on the page you send and only after that it showed the CSRF error... I reverted the changes (except for the post max size) but it still keeps redirecting me to the login panel like before... No errors, no anything...

Solved the issue by setting session.auto_start to off instead of on

Thanks for your help
