Unable to process payment due to a communications error

I'm thinking that maybe things might have changed in 6 years.

Let us know your ZC version, PHP version, and Square WebPay version.

You might try posting this in the square_Webpay support thread, but it kind of looks like the site's not receiving its access token.

i would suggest reviewing the zen-cart square documentation.

the error message is pretty clear.

ensuring the your application is properly provisioned, and that you have a valid OAuth token can some times be a challenge.

but you are communicating with square, and square is telling you what is wrong.

best.
