I had wind pretty much all night with some gust and still getting the 
error.  Also, I am not understanding 100% how this extension works. I have 
installed the Stacked Windrose also, it is putting the .png file in the 
/var/www/html/weewx folder, but when I open my local index.html in 
Chromium, it does not appear.  Can only view when I click on picture.  Are 
the Highcharts and windrose supposed to be incorporated into the html file?

Thanks!
