Issue with fog of war

So i created a new campaing and when i tried to use the fog of war the whole map became pitch black, making me unable to edit further since i can't see anything. Is there a way to fix this? Without fow(revealed area), with fow, and the pitch black that i'm getting. Also, this is only happening on the first page i created, the fow is working normally on the other maps.

When you say you can't edit any further, do you mean you can't select things while the FoW is there, or it's simply too dark for you to see?

Go into that Page's Page settings (under the blue button at the top). Change the Fog Of War GM Opacity setting for that page there & save it. <a href="https://wiki.roll20.net/Page_Settings" rel="nofollow">https://wiki.roll20.net/Page_Settings</a>

Thanks for the help, i'll do it.

Pedro, let me know if that advice resolves your issue.
