[MODULE] WHMCS

[charityz2]

Hey, 


Installed the module to Sentora no problems there, I added the module to WHMCS and it still works fine but I try and create a server using the module it shows the following:
URL: https://domain.tld/whmcs/configservers.php

When I remove the module the page beings to work again but adding it back and the same things happens.
I have the correct hostname, IP, Name servers and Access Hash set-up which I am not going to show for obvious reasons.

Any ideas?

Thanks!
