Help!!!

I'm getting a strange pop up in the center of my battle map titled "Nameless One" and it has a list of all the NPC's I've created for the game that have stats. They all have '???' beside their names. I can't delete or close the popup, only minimize it to a small, transparent box. If someone can tell me how to fix this that would be great!! 

Are you the owner of the campaign? If not is the owner running any Mods (API scripts)?  Are you running any extensions?  Which browser are you using?  Does it happen if you try your browser's privacy or incognito mode?  Can you provide a screenshot of your game please? 

I deleted all the extensions  I am on a mac and I am using Chrome. are there extensions that I should be running? this is what im' seeing I can't removie or manipulate the screen those 2 boxes are what I see.  thank you.

I am sorry, can you please supply the full (not cropped) screenshot of your game? Thank you.  Please try Chrome's incognito mode, just to make sure that nothing is interfering with it.  Extensions often interfere with Roll20's operation, trying to make sure that there are none doing so in this case.  What character sheet is your game set to? Does the problem persist when you refresh the browser?  Does it come back automatically after you refresh or only after you do something?

So I opened in the Incongnito and removed all extensions and it has disappeared.  Thank you for taking the time to help me.

If you figure out which extension caused it I'd be interested to know.  Good luck :)

I took all the ones I had on there out. Are there some that I should have?

There is no way for me to know which extensions you are using, what they do, or if they would interfere with Roll20. Only you can determine that.  To determine which extension(s) are interfering you turn them on one at a time and test, see if there is an issue. Repeat with the next extension.  That assumes you care enough to run those extensions while using Roll20. You might not. :)
