I am using QGIS-server (2.14) for publishing online maps and everything seems to work fine except for the output of the GetPrint request.
Indeed, only the scale, the title and the label of the legend is displayed but not the map realized in the print composer (QGIS 2.14).
In the GetProjectSettings response, I have my print templates but the URL that I use (based on the QGIS documentation and tested under Chrome and Firefox):
Didn't display my layers/map cf.
Do you have any idea to fix the problem?
