After updating to WP 3.5.2 everything seemed to work fine but the links to all the "Pages" on my site (not post) show a 404 when trying to enter. Posts work fine. What's wrong? My site is now completely broken and can't figure out how to fix it.
The pages are still on the CMS, with the content and links OK, it's just when I enter any page it shows a 404 instead of the content, even though the link is fine.
I disabled all plugins and tried with different templates, same result.
