I'm not sure what you mean here.. the module has no support whatsoever for URI Mappings for attributes, only for products. How is your site generating URI Mappings when you are adding attributes?

Or do you mean that when you were adding attributes you were also updating the products (possibly with a new description) and therefore generating a URI Mapping? (I think that's what you mean). Regardless, I'm pretty sure I have the solution below..

I think you mean "Added to the cart"?

It's not quite a configuration issue.. I've noticed that your site will redirect to the URI Mapping entered in the admin when you go to the product page but *no* links use the URI Mapping. This means you've forgotten to upload the new version of

includes/functions/html_output.php

from the modified_core_files folder (for your version of ZC).

That means that the form action URIs are being set to the old dynamic Zen Cart URIs, so the forms are being posted to an old URI and then having to be redirected to the new URI. Since redirections don't re-post values the items aren't being added to the cart.

Hope that gets you up and running.

All the best...
