Based on Adam and my findings there is a potential compatibility issue with WHMCS V8.X, possibly as a result of changes made to the WHMCS backend that's causing issues with the redirects when you submit/reply to a ticket.
Submitting a reply or creating a new ticket via the client area in WHMCS results in a blank page, with no errors logged.
Versions running the latest 7.X versions of WHMCS are working as expected.
