I'm not sure what happened to my site, I upgraded to the newest version, and everything was fine for a few days.
Then the theme stopped working. All my page and post content now shows up in the left column where the menu is, and all the right column shows up where the content used to be, and it's stretched out to the size the content would have been.
I don't have any plugins added, that I know of, that are not compatible. I have my site in maintenance mode now because I can't get the content added.
I have uninstalled the theme and started over, but it still does the same thing. I put in an older version of the theme and the content doesn't show up at all.
