Redirecting problem

I have had to disable vbseo 3.5 because it was not allowing visitors to see the forum homepage, error on browser said that the page could not redirect properly. But was fine when I went to the forum, so only the main cms area was affected.

This is the firefox error - "This problem can sometimes be caused by disabling or refusing to accept
cookies." I have had to enable again because of all the changes I have done to urls. Can anyone tell if there is simple that I have done wrong? you can see what ther problem is by going to www.intospain.com

Can't leave it like this so disabled cms rewrite
