I’ve gone through the extensive support threads in regards to Pagination. and have yet to solve this. To prevent redundancy I will outline in order what I have done so far:
1. Disabled all plugins
2. Flush and reset Permalinks in the Permalinks settings menu.
3. Erase and replace .htaccess file
4. Tried several variations/reorganizations of the query code
5. Set my ‘blogs show at most’ to 1 ( lower than my ‘posts_per_page’) in Reading Settings.
7. Checked that there is no conflicting URL slugs.
Finally I put a <? print_r($wp_query->query); ?> at the end of my page I’m having trouble with and my 404.php page.
