Problem With Add To Cart Button On Featured Products

[CTF-OK]

We noticed that on the Add to Cart button on the module: Featured products on the homepage was giving an error on all products listed.  Error: Product not found.  This product is no longer available.  If you click on the image or the More button and go in to the product page, the Add to Cart button works fine.  I just found out that it also fails in the category pages as well.  

 

I have tried searching the forums and the web, but none of the advice works.  Thought about just deleting the button from the featured products, but couldn't find a solution.  Added a module called Featured category products on the homepage v1.5 - by MyPresta.eu and it too has the Add to Cart error.  We are using 1.6.1.4  and the site is http://www.creationtruth.com/storetest2015/

 

Thanks!

The odd thing is that it's not triggering any ajax on the product page. It's also adding random products to the ajax cart, although they do not display in the checkout. Do you have any extra module related to cart features?

Thanks for your advise!  Yes, I did have another module that I didn't need affecting the button.  Disabled it and now the button works!  You are right about the random products being put into the cart, or at least that is how it looks on the dropdown.  They aren't actually in the cart when I go to check out.  Weird.  

 

Also, now that the button is working, when I add something to the cart, the popup is wider than the page and you have to scroll right to see all of it.

 

Thanks again for the response!
