I have permalinks set to "Post name".
If I put in my address bar: http://www.example.com/section1/whitepapers/, WordPress loads it correctly, but if I send a POST or GET request to the same URL, it throws a 404 error inside WordPress.
This is my htaccess file: https://gist.github.com/3062205
Could someone shed a light on what might be happening here?
NOTE: The 404 error is thrown by WordPress, it's not a Server 404 message.
