The auto login seems to work fine in my website, but I am redirected to a page http://cyber-minds.net/portal/error.php?c=1, which says that "Why am I being redirected here?

Cyber-Minds.Net - Internet Psychology site security has detected that your computer has a firewall setting that is preventing you from registering on the site. We use 'Referrer-checking' know as HTTP_REFERER which makes sure that all contents posted are from authorised users only.

I followed the instructions about cookies, firewall setting, but I keep gueting this message everytime I reestart my internet explorer.

Why is happenning that? How can I take out this message error?
Thanks.
