Is this happening to everyone or just you? Have you tried clearing your cache? Have you tried it with a different browser to see if you get the same results? And, have you changed your cookie settings in your vboptions > Cookies? (Also, you said it takes you back to the login page and not the index.... but isn't
www.racersweb.com your home or index page?)
I just checked and if you click on the links, you are taken to racersweb.com/thislink.php... not to
www.racersweb.com/thislink.php. You should try to be consistant in what is to be used or you could end up with this sort of login issue.
