My websitelooks fine in Safari 5.1.7 and Firefox 13.0.1 and the wp-login and dashboard look normal in Safari, but in Firefox 13.0.1, the formatting is stripped. Instead of the menu appearing on the left, it appears as an outline at the top of the page. I haven't logged into my site in more than a week—it looked fine last I checked—and I haven't made any changes to it.
Any idea what's causing the problem and how I can fix it? Thanks!
