My host provider recently upgraded to asp.net 4.5 and my site running kentico 6 on asp.net 3.5 suddenly stopped showing charts.
The system has produced a charting error with the system.datavisualization.charting namespace and a web.config reference to the handler.
My host provider suggested I investigate compatibility issues between asp.net 3.5 and 4.5 in the charting.axd handler - has anyone come across this yet?
thanks all. morgz.
