I have inherited a webmap that seems to have a pop up enabled where there is no data. I need to change the wording on this but I can't work out how this pop up works.
Does anyone have an idea of how this pop up was achieved and how I can alter it?
this is the link to the app which used the webmap.
Where you can see if you click on a blank area of the map a box will come up with the message "no data available" I need to change this message.
