Some users experience problems with using the heatmap functionality on the web interface. When opening the console they see following message:
> Failed to load resource: net::ERR_BLOCKED_BY_CLIENT
> Uncaught Error: Script error for "heatmap", needed by:
The problem will occur when you're using the AdBlocker extension in your browser. Apparently the Heatmap.js library, which we are using in the web interface, is in the blocked list of AdBlocker. The problem is already reported on the Heatmap.js Github repository; however no solution has been reported until now.
The only solution available for now is to whitelist the web interface.
