Just wanted to say a huge thanks to @Rhett for fixing the connection issue I had with the callback to the licence server, after changing the url for my test install of V4 the main site wasn't able to call back to invision.

Several checks done but Rhett found the problem at IPS's end and the issue is resolved. This is why I choose IPS above others, the service is just smiles better.

Thanks Craig, glad to help
