Yosemite: can't get apps on Mac App Store I upgraded from Mac OS Mavericks 10.9.5 to Mac OS Yosemite 10.10.1 and have issues with Mac App Store.

If I search for an item, I get results, but if I click a result, I get a blank page, whatever the app's page I want to see.



As you can see, the classic app background doesn't even appear.

I do not experience this issue on a fresh install of Yosemite in another mac, so I did bought my app on the other mac and used the search results's menu to install it on the right one, but that's quite tricky.

I tried to reboot, to reset the PRAM and other stuffs I seen over the internet, but didn't found any good answer.

FYI:
Try resetting the Mac App Store.


Enable the debug menu and restart the Mac App Store.

defaults write com.apple.appstore ShowDebugMenu -bool true

Choose the Reset Application option and restart the Mac App Store.
