Logout doesn’t work on theme

When I click logout on my theme at the comments, I first got the typical ‘You are trying to logout’ bug, searched and found the fix.

This is my code now:

<p>Logged in as /wp-admin/profile.php”><?php echo $user_identity; ?>. ” title=”Log out of this account”>Log out »

However, I get a 500 internal server error when I click it now!

This address in my bar during the error:

http://www.bestofonlinegames.com/wp-login.php?action=logout&redirect_to=http%3A%2F%2Fwww.bestofonlinegames.com%2F%3Fp%3D89&_wpnonce=1d61efeb78

What should I do?
