I am using custom post types and some other new wordpress 3 features and y permalinks are busted. If i edit a page, /%postname%/ permalinks do not work anymore and i have to revert to ugly url links, then switch back to postname. I have seen many people on here with the same issue, but i cannot find a resolution. Site is not live yet because of the issue so i can't offer a link to the problem. VERY FRUSTRATING!!!!
