For our Umbraco 7.5.6 project running Merchello v2.4.0 with FastTrack as the base, we are trying to implement Braintree as the payment provider. I am currently using the Braintree Sandbox to try to test.

When I use the "No Credit Card Errors" credit card numbers as provided by Braintree (https://developers.braintreepayments.com/reference/general/testing/dotnet#no-credit-card-errors), the transaction is not completing and is not showing any logged attempts in the Braintree Sandbox account.

Here is a sample log error for each attempt: 2017-06-26 10:33:19,471 [P23820/D40/T795] WARN Merchello.Web.Caching.VirtualContentCache`2[[Merchello.Web.Models.VirtualContent.IProductContent, Merchello.Web, Version=2.4.6240.24751, Culture=neutral, PublicKeyToken=null],[Merchello.Core.Models.IProduct, Merchello.Core, Version=2.4.6240.24748, Culture=neutral, PublicKeyToken=null]] - Could not map all items to virtual content

Does anyone know what this means? I have been stuck on this for quite a while and need to get this payment provider tested and launched. What am I missing?

NOTE: We are also currently experiencing issues where the invoices processed, using PayPal for payment, are not rendering the invoice details in the Merchello > Sales > Invoice# view in Umbraco Back Office. We are suspecting that there are some permissions issues in play preventing Merchello/Umbraco from managing the indexing of the invoices. Using Examine to re-index is not resolving the issue.
