I have a few articles on my site that show track information. Usually it is just the map. For some time now the maps are not showing anymore. Just a blank on the place where it should be. 

On my local site using xampp it works juist fine. I have been looking for some time now what the issue can be, but can not find it. Both installations are completely up to date and I can not fiund any differences. The code used in my article is shown below.

{GPSCONTENT ["id": 111, "elevation": 0, "speed": 0, "hr": 0, "trackinfo": 0, "waypoints": 0]}

Any idea where I have to look for the solution?
