I've got a new Zen Cart installation (latest versions of everything) going and I've just installed Simple SEO. It works beautifully for category and product listing pages, but it seems like the "exceptions" aren't working. I've got all the default exceptions in, yet when I click "add to cart" it tries to go here: http://xxx.com/store/pc-it/1/sort/20a/action

I suspect the issue might be that a tech before me modified the product listing module which now draws the "add to cart" buttons in a form like so (I've removed the var it's adding to, there's no syntax error here)

Code:
zen_draw_form('add_product_'.$listing->fields['products_id'], zen_href_link(zen_get_info_page($listing->fields['products_id']), zen_get_all_get_params(array('action')) . 'action=add_product'), 'post', 'enctype="multipart/form-data"');
zen_draw_hidden_field('products_id', (int)$listing->fields['products_id']);
any ideas?
