Add to cart button - bad link

My template is giving me trouble. Here is the site, https://www.displaysignboard.com , if you try to add an item to cart from the CATEGORY page instead of the product detail page, it will give error. I have narrowed it down the problem to the link on the category pages. There is a index.php that shouldn't be in the links. Can someone tell me how to get rid of this? any idea where to change this? Thanks! greatly appreciate any help.

If you turn off the SEO URL add on, you have does it work?

yes it does work when i turn off SSU. Anyway to fix this?

It's more than likely your template creates a bad form of add to cart links on those pages.
I would do this to debug:

1. turn of the seo module
2. view the source code of the page to see how the form action link looks like, is there anything weird with it?

Alternatively, you can check the module and template code for the category listing directly, and see if there is something wrong.

Another thing you can also check is to switch back to default template (provided that you used the template override system correctly), and see if the link generated there work correctly.

I am still new to all of this so it'll be hard for me to spot errors even if i knew how to check the code for categories, which i don't. I know it's a problem with the template since everything works fine in another cart in which i am running ssu with zen cart. Can someone break down for me where to check the categories link action step by step? thanks.

Since you also got some error last time with the category sidebox links in bad form, I would assume you get a badly coded template.

Anyhow, I would check the file includes/modules/products_listing.php or includes/modules/your_template/products_listing.php

thanks a great deal. Got it fixed. Yes this template is badly written, will avoid in future.
