Removing “»” from sidebar

I can’t seem to remove the » that appears next to links in the sidebar. I’ve never had any problem in the past, but with my current project (the first time I’ve used 2.2) there’s nothing I can do to remove the darn things.

What I’ve tried:

— list-style-image:none and list-style-type:none for every id/class in the sidebar, including the .page_item that appears with my wp_list_pages function.

— removing the “page_item” list item class in wp-includes/classes.php (a tip from this guy)

— removing the » before page titles in title bar by editing wp-includes/general-template.php (another tip from that guy.)

This only seems to affect the sidebar when I load it in Firefox (2.0 — PC). Looks fine in IE.

When I use the “default” template, I get the » . When I customize sidebar.php, it’s replaced with two question marks (??).

I examined the code, and it looks like they are indeed list item bullets, and the li class is page_item — but I cannot remove them.

Here’s the site.

What am I missing here?
