Issue: Blog issues

I was trying to customize the colors of my background, font, etc on my blog here tonight and no matter how many times I hit save, and save changes on the customize blog settings thingy it still kept going back to the old colors and such I had set before.
I didnt bother with changing it before due to how difficult it was to change it in the first place but to make it easier to read I figured I had the time to fiddle with it and change it around, but now it wont let me.
