I'm having a hard time as to why this is happening. I have website that has a 3 level deep menu using Categories.
>> 2nd level
>> 3rd level
Any time I view a 2nd or 3rd level category, I'm getting back my 404.php page?? I have tried adding a post to all the categories but nothing seems to work?? Can WP Categories support this functionality or do I have to rely on pages to give this kind of structure?
By the way this structure is needed as the URL's are essential for our SEO.
