[SOLVED] Exclude pages works on Chrome but not on FF or IE

Hi,

After two years uptime using Atahualpa 3.4.1, and a recent server migration by my host, the page menu is now showing pages that are excluded in theme options in both IE and FF. Chrome renders as it should. I've disabled plugins, no change. Even trashed pages and they still show. What gives?

Thanks for taking a look, this one's baffling!
