solved the poroblem with using 404sef

Hi,

I have a login-problem with checkout form. Every time users try to login from cart with sef switched on, they get back to the same (login)page. Without sef anything works fine.

This loop doesn't appear at joomla login. What is going wrong? Any ideas?

joomla! + virtuemart 1.012
artio sef v2.2.2
