Fix an error in my unity game

This project needs someone who is familiar with Unity 3D and Photon unity network. * I have an online game and everything was going well, after upgrading to Unity 5.4 i got a problem when trying to play the game in WebGl.

Also here's a thread that i guess may help you understand what's going on: [login to view URL] It's very simple for the one who knows what he is doing, budget for this is $20 Thanks, Abanoub
