Can't access Theme/Online Store "Page"

[extravaganza]

When I click "Online Store", it doesn't load (?)

"Status page" is perfectly fine. All other pages are accessible.

Yeah, I've tried reloading, cleaning cache, reloading browser and all the standard things.. please help!

I can't access the theme since hours

[extravaganza]

Just for anybody curious for the answer;

My problem got solved "magically", I couldn't access the theme for about 12 hours. But now it works just perfectly fine.
