I've noticed that every time I click post for a comment, a page appears with this random coding that has the comment in it. Others are getting this too, and hitting refresh thinking their post didn't go through. Ok, here's what you do.

Just hit the back button to go back to the blog you were posting on. The comment will be there, and you won't accidentally double-post from hitting refresh. There will also be a pink/red box on top with random coding in it too, but it seems to be harmless. Just ignore it for now, and hopefully the problem will be fixed soon.
