I'm having a huge problem with the way my permalinks are structured. No matter what format I use, another problem shows up.
I'm currently using /%category%/%post_id% as my default. Everything works, including page links (e.x. http://controlalttv.net/column). However when I use <?php next_posts_link('Next Page') ?>, I get a 404 error (see http://controlalttv.net/column for an example)
I want to use /%category%/%postname% instead. Links and pages work but when I want use second-level category (i.e. Category/category), I get a 404 error.
Any idea on how to fix this?
Thanks,
Gregory
