Custom module not working on 7.3 issue with require statement

[TeleMagic]

Hi Guys

I am trying to get a custom provisioning module we have working on a new 7.3 installation. It works fine on 6.3 but is failing on 7.3

I have narrowed it down to the following line,

    require 'class.VcsApi.php';
I have copied the contents of this file to the bottom of my module and it works fine, So im guessing it is an issue with the way the new version handles require's in the php code.

I was advised by Support that it might be related to relevant paths, however I have tried a number of options here and none seem to work.

 

Anyone have any idea I would appreciate it.
