Black Screen

i am having an issue with logging in as a player from the DM screen.  When I do, I can't see anything, even on just a whiteboard.  I have tried logging in as a player from several devices and always get the same result.  I created a free about and added it to the game as a player.  Logged in and same issue.  Just black screen.  Everything else is there but no map.  Suggestions?

I just created a new game. Loaded a map and switch back and forth between GM and player, worked fine. Added lighting functions and when I switch over as a player....black screen.  Not sure what is going on.  

Hi, make sure you have a token set up with 'has sight' ticked. They also need light sources to see with, for testing i would suggest setting the token to 'emit' it's own light (i use 10' dimming at -10' to create the illusion of being able to just about see in very low light.) You will also need to make sure that your page has the following settings enabled: Dynamic lighting = yes fog of war = no (if you use fog of war along side DL you will need to have made sure to clear an area that the 'player' could see in first) enforce line of sight = yes (this and the 'has sight' option on a token are essential to getting DL to work). restrict movement = optional, means that players can't move through DL lines although a single pixel gap will allow them to. For more details and a walkthrough check out the  wiki . Let me know if there are any other issues as play here.
