Apologies in advance for being such a newb (1 week with CSS). I noticed a little while ago that the administrator bar on my blog has disappeared. The bar was there last night and I did not make any changes to the CSS. After noticing the bar was gone, I looked at the code and found a reference to a header image that I've not used in many months. Removing it did not fix the problem. (I'm using Firefox. The admin bar appears normally in IE. Clearing the Firefox cache didn't help.) I'm at a loss as to what else to try.
The blog I need help with is piedtype.com.
