Two Items Added When Added to Cart

[nastea 0]

When adding products to the cart, I'm getting two products added. I'm sure it is an easy problem but not sure where to even start. You find a product, click add after clicking size etc. Then when it takes you to the cart you have two added.

Any pointers?

What version of osC are you using? What add-ons did you install or did you install any add-on that could affect the add to cart button or the shopping_cart.php file?

Did it ever work before?

It did work before, I have quite a few addons, it started happening after I loaded QTPro but the admin/author of that addon hasn't replied. So I figured I'd at least get someone to tell me where I can look. It worked fine before the QTpro load and I'm using 2.3.4.

Here is the shopping_cart.php

The file shopping_cart.php is not relevant

 

Post the lines from your file includes/application_top.php, only the "case: add_product"

 

that start with

      case 'add_product' :    if (isset($HTTP_POST_VARS['products_id']) && is_numeric($HTTP_POST_VARS['products_id'])) {

and end with

                              tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                              break;
      // customer removes a product from their shopping cart
