I just added a new category and three sub categories and now a bunch of categories just don't display when you select them. All categories display fine from the index until you get to a certain point then no further ones will display.
Some of the categories that will not display were there and working fine until I added this last category.
My URL is here http://www.axecity.com/classifieds/index.php
They stop displaying properly at Learning Materials. All categories after that display only the top headers and leave the rest of the page blank.
The category I added was "Guitar Techs"
Your help would be greatly appreciated.
