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.
