Why does my forum look so weird?

I am not sure what is wrong. Help?

http://engl101-6.forumotion.com/

Try http://hitskin.com/

That didn't work, but when I changed it to an invisionfree format it corrected itself...

Solved?

Hah, go to Admin Panel => Display => Skins => Choose a theme => Version => Change version : Invision; Choose your style : Version default style;

Skins => Choose a theme => Skins, see the red version? Click on it then Save Settings.
