No heatmap is rendered (logs are created tho)

Hi there,
Was trying to install this module on our production server.

Installed the module in sites/all/modules/click_heatmap and copied the library files to .../click_heatmap/clickheat
enabled the module
set the permissions for all roles to record clicks
set the permissions for the LOGS , CONFIG AND CACHE folders to writeable and

tested the implementation on the homepage (where I told clickheat to count) by adding the debugging - parameter - all seemed to go well.

Looking at the logs folder , it seems that another folder has been created with my data in (sitename + pagename) but when I go to look at the data I get NO heatmap whatsoever.
All I get is what's in attach .... my admin_menu bar overlayed with a clickheat error (asking me if I installed the javascript correctly)

Anyone ?
