I have a really bizarre problem that has me totally stumped. I'm working with a client and she has a website that is powered by wordpress (running 2.9.2) with a fairly substantial number of posts but only a handful of pages. She hasn't had the need to create new pages until recently - and that is when we discovered that all new pages that get created throw a 404 error. Pages that already existed are fine and show up without any problems - it's just new ones. New posts also are showing up fine. It's just pages that are having the issue.
In an effort to troubleshoot this, I turned off all plugins, and removed any customizations in the htaccess - nothing here had any effect. We have the permalink setup as: /%category%/%postname%/ - changing this to anything else did not have any effect - except when I changed it to the DEFAULT (index.php?p=1234) setup. (That's great - but obviously for SEO reasons, we want to have a permalink structure)
And here is the weirdest part... I have a test site setup on another server... figured I'd copy the site over to play with on the test site - but when I moved it over, (and changed the settings to have it all point to the test site) - the problem didn't exist there. So maybe it's also a server config issue? (Both servers are running PHP 5 - but slightly different versions: 5.2.10 on the one with the issues, 5.2.13 on the test server.
Any help/suggestions of things to try would be greatly appreciated!!
