Blogger Bug: Dynamic View faces some problems on all of my blogs

Something is wrong with dynamic views on Blogger.com.-
The background picture disappeared and only comes back when pressing Shift-Reload, vanishes just after another reload of the page, and the Google+ comments disappeared in the same way.

I double checked the settings, although I didn't alter them for a while now. Seems definitely a blogger.com bug. This is happening to all of my dynamic view blogs. *Sigh*
