UPDATED on April 15th, 2019:

I am trying to set this up on Magento 1.9.4 but it does not appear to be working. It gives the following Error:

There has been an error processing your request Exception printing is disabled by default for security reasons.

Error log record number: 1248949596922

This is the content of that Error log:
