WHMCS Module on PHP 7.1 server dead.

[aaronlroberts]

I've been using the WHMCS module on my server for a while now, but now that WHMCS has added support for PHP 7.1, and it is required for the new version. The WHMCS installation is NOT on the same server as the one which the hosting account will be created. They are 2 separate servers, and this worked fine before.

It seems that the module dies upon executing the command to do anything with the sentora server via the module. 2 lines are output in the error log as follows:

Note: I had to add spaced between the # and a number as this forum replaces it with another thread title. I also removed my domain information / folder structure from the logs too.
