Resource ID was not found

[Robin Cantrill-Fenwick]

Hi everyone,

Apologies that this is the very worst kind of "I'm getting this error...." email, because it's really vague.  Just wondering if it points to something obvious that we can investigate.

We are using Omnipay as an extension to CiviCRM, integrated with Wordpress. We use the PayPal checkout integration. It's absolutely great, but some transactions (as yet with nothing we can spot that obviously links them) are failing with this error

"Sorry there was an error processing your payment. Please try again later. The requested resource ID was not found."

I'd be grateful for any tips on further debugging - what the Resource ID is in this context, whether this is the right community, or if I should be doing this over on some CiviCRM boards etc.

Yours in n00bieness,

Robin
