Serious New Problem

[AntiNSA2]

I have just noticed that one of my categories name (cat26) has taken over the description name for each category. The category description is correct, and in the clickstrem it shows the proper category name. However when clicking on the category from the home page, when you look in the body of categories, you see that every category name is named (cat26). This is a strange error I just noticed.. but I need to fix. What could be causing one category  name to be taking over the other category names on categories.html ?

Thanks for your help... this is crazy.

IT is the {cat_name} tag which does this

Yes, {cat_name} is the correct tag.
Something along the way you've changed in categories.php
Search for cat_name, maybe you'll find something unusual.
