Help! My permalinks have suddenly stopped working. I have had them set up as follows: /archives/%postname%/ almost since I began the blog in January, and they have worked fine. I was barely even in the WP Admin this weekend and haven't done a thing in ages except write posts and manage comments (no new plugins, upgrades, etc.), and suddenly I get the system 404 (not the 404 page from my template) when clicking on any permalink. I tried changing them to the default, and they work fine, and then changed them to date and name based and that works fine as well, but any permalink structure that begins with /archive/ returns a 404.
I tried deleting the htaccess and changing them again, but that did not help. I would appreciate any ideas anyone has.
