The App Store had operational problems following the launch of iTunes 11

  After the launch iTunes 11, the App Store had some problems rendering correctly the graphic elements that users can interact with, some of you emailing me images that essentially display the same thing. Basically, instead of the names of the applications and the buttons, the code from the images above was displayed and the whole problem has to do with Apple, not with you. At the moment the problem seems to have been solved, but if you encounter it, you don't have to be scared because you are not the source of it.

  Only the App Store for iOS seems to have had problems, the desktop version remaining unaffected.

Thanks to Mihai.
