I am using Zen Cart 1.3.9d
The only addons I have installed are Google Analytics and a Shopping Cart with Checkout button mod.

I have uploaded all of the CEON Uri files, with the exception of:

admin\includes\functions\extra functions\ceon_uri_mapping.php
(causes white screen in admin)

admin\categories.php
(causes blank page when accessing edit mode in a category)

What would cause this one file to break admin?

Thanks,

Josh
