Hi Collin,
Unfortunately the customer did not take a screenshot or copy the error verbatim. Here is how they described it:
[On the WordPress site] I put in my personal information and registered. Once you submit that, you are re-directed to the Paypal site to pay the $185 fee. That is where I am running into trouble. I enter in all the payment info, and have verified it is accurate, but once I hit submit, it says there is a problem right now and to try again. I went through that three times. I don’t know if it is an issue on Paypal’s end or [the WordPress site].
I can ask them to try paying again if that would be helpful.
