Module Works on 6.3 but not 7.0

[TheHostingHeroes]

Hello

 

We have our own module developed for our VPS Resellers, it works fine in WHMCS v6.3.1 but not WHMCS 7 (7.0.1)

 

on the product > module section all items are missing on V7

 

Has something changed in WHMCS v7 to cause this? if so where can I find what changes are needed for modules to work.

 

PHP version remains the same 5.6

 

for testing today we setup a 6.3 install, it worked fine. We then upgraded it to v7 and the module no longer worked.

 

Screen shots attached from v6 and v7

 

V6:

 

V7:

 

I tried adding error_reporting(-1); to our CyberHostPro.php but I didn't get anything useful out of it.

 

Hoping someone can help me
