Help Please: Session in URL problem

Hi everyone,

I'm makign custom templates for my board and when I put in the links for the different sections like register, search, memberlist, etc., when I open up the page the url shows this (for example my registration link):

http://www.dnforum.com/register.php?s=Array%5Bsessionhash%5D&action=signu p

Is there something vital I accidently missed transfering from the old to new templates? Anyone know what could be the problem?

Thanks,
Dan
