Hi,
I have tried to add the code as you mentioned. But it now some other place instead of chicago. Since there is no option to attach image here, i am unable to add the screen shot for the same.
I have tried to add Chicago with following code, but nothing happened.
[‘Chicago, US’, 41.8781, 87.6298, 4],
Also the chat plugin is showing, but I dont know how to administrate it without any admin page.
I did the same.
