Nothing Happens at Checkout - RESOLVED!

[AndyD]

Can put items in cart and proceed through the checkout process, but when you click "place order" a wheel gif spins for about 1 second, then nothing happens. The order in not placed. 

We received donations in February, and have added a few items since then, but now I am not able to check out with any item.  Super frustrating, we are starting a fundraiser tomorrow, and I can't sell any tickets!

I did add some custom code to remove the quantity option, but the behavior is the same when the custom code is removed.

I seem to have resolved this issue.

The domain name for the website has recently changed. Disconnecting & re-connecting our Square Account seems to have solved the problem. I assume Square was expecting to see the old URL for purchases and therefore was not processing orders associated with the new URL. It makes sense that a new connection to Square would give it a handshake with the new URL.
