Dynamic Lighting Issue

I am having a problem with one of the players dynamic lighting working properly. He can see through the walls that are on the dynamic lighting layer. The dynamic lighting is working fine for my other 4 players and myself. When I look at his token through the player perspective it is working fine. I am using google chrome on my end and he is using firefox. Any help or tips are appreciated.

Is there any chance you and your player could both provide screen shots of this issue? I don't think the problem is on your end. Also, does your player have the same view if they use google chrome instead of firefox?

I will attempt to get screenshots tomorrow night during our next game. I don't know if he has tried using chrome, I know he had the same issue with internet explorer. He says he does not have a problem in other games, just mine.

He used Chrome this last session and it worked fine. Thanks for the advice.

One of my players had the same problem for one session. The next session the DL worked again. He uses Firefox.
