Hi and thanks for getting back to me!
Code for shopping cart icon looks like this
<input type=’image’ src=’http://shadybridgefarm.com/content/wp-content/plugins/services/webpages/util/2/t/2t2z6dl4s.site.aplus.net/shadybridgefarm.com/public/content/wordpress-content/plugins/wordpress-simple-paypal-shopping-cart/images/shopping_cart_icon.png’
When you enter that URL alone in the browser window, it does not work.
I don’t have a caching plugin. I have very few plugins and it’s a new installation.
