Registration verification problem

[ski diva]

I have my forum set up to send a new member an email in which there's a link they have to click on to activate their account. However, when I click on the link I'm presented with a message that states "the request URL/register.php was not found on this server."

Is there something I need to change in vbulletin, or is this something I need to address with my server?

Have you set your Forum URL through the vB Options panel?
