How are you checking the token's vision? Are you using Ctrl-L or 'Rejoin as Player'? If so, create a Dummy Account to check token vision instead. Ctrl-L does not show a player's view from a token (but it should show a token's Line of Sight... so it should work, but it still a good idea.) Make sure to move the token at least one space. There was a bug previously that token vision did not 'update' until the token has been moved on a page. Is the token able to see if you turn on Daylight Mode? If yes, then the problem is with the light source. If no, then the problem is with the token settings (and also maybe with the light source, but you can rule out the token vision settings.) Definitely check if you have any Permanent Darkness over the area - that is not controlled on the Page Settings, but from Darkness Tool on the left toolbar. If you have everything set up correctly but an area of Permanent Darkness coving the token, your screenshot is exactly what you would see. Separately, you'll probably want to turn on the 'Dynamic Lighting Barriers Restrict Movement' setting, or else your players will be able to move through your walls and possibly spoil future areas. I also suggest turning on 'Update When Token Drop' so that players cannot move their tokens around and land back in the original location, which means that you wouldn't see any movement but they will temporarily be able to see those areas. And my preference is to not use Explorer Mode, and use ' Light Crumbs ' instead, but your mileage may vary.
