I just updated to WordPress 3.9.1, and since I did, my journal's setup is completely messed up. I had an author's list on the left, which has disappeared; and all of my entries (some of which go back 20 years) are completely out of order - the only way I can get to the most recent entries is by choosing the current month in the archive, and even then the order of the entries has been changed from most recent first to least recent first.
I'm not very technical-minded, and I've been all over the Internet, trying to work out how either to fix it or to downgrade back to the version (3.1.2?) I was using before, so I could really use some help.
I'm using the Greening theme, with two (I think) plugins and a few widgets.
