Shopping Cart Button not appearing with Simple Paypal Shopping Cart 3.8.1

I’ve upgraded to NextGen 2.017 and Simple Paypal Shopping Cart 3.8.1. The button for adding the product to the shopping cart no longer appears.

– The code I’m using to display the descriptive text and button is [nggallery id=1 template=wp-cart], because [nggallery id=1 template=wp-eStore] gives me an error message that the template is invalid.

– The ‘View’ folder is not part of the most recent upgrade of NextGen, so I added it manually and uploaded the ‘gallery-wp-eStore.php’ file there. I also added it here: /public_html/wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_templates/templates
