Heatmap & Session :: resulted in an error: curl_exec

Hi,

This seems to be the same reasoning as here:

Error configuration with Heatmap & Session Recording Tracking

Hi, For Heatmap & Session Recording to work correctly the /plugins/HeatmapSessionRecording/configs.php URL has to be reachable for all website visitors.

As long as your visitors can access this URL and get the Piwik.HeatmapSessionRecording.configuration... response, everything should be working fine.
