Log out does now work

the log out is not working in your theme, it loops user into wp-login page and redirect is not returning user back to home_url

I've tried setting back the defaul theme, and there is works perfectly when user clicks:

http://kehitys.eek.fi/wp-login.php?action=logout&_wpnonce=a7de7e503c&redirect_to=http%3A%2F%2Fkehitys.eek.fi%2F%3Floggedout%3Dtrue

But when using the sportPress theme, it aint working, anyone having same issues?
