Blogger acting weird

For some reason Blogger is making some weird things with template. For example RSS icon is gone from the top, but the worst thing is that usually, the post background should be dark-gray and text white, then now blogger suddenly decided to change the background color to white aswell, that makes the text impossible to read.
I have tryied in many ways to change the color back, but nothing is working. However I can easily change text color and that works straight away.
I dont know what is causing this, but I hope everything will be fine soon. I've changed text color to black for now so it is still readable.
