I'm investigating and had found that if I change my permalink wp works.
Right now I'm using: /index.php/%postname%/%year%/%monthnum%/%day% that doesn't works. Default works, also /index.php/%year%/%monthnum%/%day%/%postname%
I think that WP 2.5 can't differenciate a page from a post if %postname% follows index.php/ anyone knows where WP 2.5 checks the url to apply permalink?
Can you post your permalinks that doesn't works so I can confirms my thoughts?
Thanks
