[SOLVED] Cannot get border off of header when centered.

I have a dashed border on my blog, katyloves.com, and even though I've deleted the border lines, it still shows up but ONLY when the menu items are centered. When I put the items left or right, there's no border. Sorry if this has already been posted, any help is greatly appreciated!

Update: Found the answer, added:

div#menu1 {
border: solid 1px #ffffff;

to CSS Inserts.
