Purchase Test

Hello David,
I am trying to add product to cart to do a test to see if the cart is working right.  I click on add to basket but nothing get added.  The square icon just spins.
I am wondering.  I am also trying to set up my payment gateway which is PayPal and the docs set up instructions don't match PayPals so having a hard time setting this up.  I need your help please.
