Dear Ben,
Thanks for the link. I think your archive PHP template is not including the main navigation so when its loaded like this (http://em.eidev.me/?cat=45) it will not include it. Can you check your archive.php or category.php template is including navigation code correctly? I checked the source code of the loaded archive and it seems the navigation HTML is empty:
<div id="nav"><div class="wrap"></div><!– end .wrap –></div>
If you can provide the following information, it will be helpful to troubleshoot this one:
1.) Can you post some code of your archive.php, category.php and header.php, if they are long. You can have them as screenshots. I will take a look at it.
2.) Have you tried enabling debugging mode in WP by adding this to your wp-config.php:
define('WP_DEBUG', true);
Then load the archive page to check if there are PHP errors on them. Turn this off after testing and report it to me if you see any PHP errors or warnings.
Thanks.
Cheers,
Emerson
