Domain problem with domain mapping

Helloo,

I’m trying to allow user to hit “Visit site” and still be in the admin side where you can see the bar up top etc. Alright this is working fine and dandy when the domain has .com (Mapped url) but when i have put up a .fi (Mapped url) the “Visit site” always logs the admin out.

Any help with this problem would be greatly appreciated 🙂 I have created a bunch of tutorials for WP as a video so this thing is rather important to fix before going live with em.
