After update problems! Icon and admin center

Hey, their I updated the theme. And now the icons don’t work anymore.

I updated the icons with the new names, but that didn’t work thought.
http://fortawesome.github.io/Font-Awesome/icons/ I used the names on the website…

http://kunkal.at/index.php/grafikdesign/
http://kunkal.at/index.php/visitenkarten/ (Found “fa fa-check fa-4x” in the support forum. But that is not the offical tagline? How am I supposed to know that name?)
http://kunkal.at/index.php/webdesign/
http://kunkal.at/ circles have no icons…

My Test Blog has some issues too. When I press Continue Reading… it will go to this URL

http://kunkal.at/index.php?/status-post-format/

And that URL just go to kunkal.at

I have the same error in the admin area as the other guy on the Forum. I uploaded a picture. Endless loading 🙁
