I have had my store set up for a while with no issues. I have PayPal Standard set up and have accepted payments with it. I have changed nothing on the store recently and this morning, I received an email from a customer that said no payment options were available. See the attached file for the issue or reproduce it online by going to wwwdotswixpixdotcom.
The shipping options are not set to a specific payment. PayPal is set to the default (and only) payment option.
The issue only seems to happen during guest checkout with no registration.
