[blocked] The page at https://wpsupport.boisestate.edu/wp-content/plugins/chartboot-for-wordpress/cbwp.php ran insecure content from http://www.google.com/jsapi.
I was able to fix the whole issue by editing cbwp.php eight lines or so from bottom to src="//www.google.com/jsapi" it was originally src="http://www.google.com/jsapi" This allows the browser to load up http or https depending on what the page is. If you could make this change in the next version I think it would be an improvement.
Got the idea from the second edit of the author's question. Not too sure if it is directly related to this issue. http://stackoverflow.com/questions/547384/where-do-you-include-the-jquery-library-from-google-jsapi-cdn
