Ok, I've read several posts now regarding 404 errors.
I never had any issue with my web hosts over the years.
I never had any issue with .htaccess or Apache.
I never had any issue with making custom Error Documents.
I had working 400, 401, 403, 404, and 500 ErrorDocuments.
However, since upgrading from WordPress 1.5.x to 2.x, they have all stopped working.
A lot of the posts where people have 404 issues seem to have nothing to do with my problem. They always trace it back to a flaky host, some htaccess issue, etc.
Even if my htaccess file contains ONLY the ErrorDocument rewrite and the WordPress Permalink rewrites, I can still never get an error doc to load. Every bad request just loads /index.php, instead of my errordocs (/error_docs/404.php for example).
It's been this way with 2.0/2.0.1/2.0.2 now. Does anyone know if this has been addressed with any nightly build?
