Bug - SCP has hardcoded http:// reference
SC+ loads the scpdetails.js file used by the Help > About dialog using a hardcoded http url. If you are running SC+ over https, browsers will not load a mixture of secure and insecure content, so the request to load the file is blocked by the browser.
e.g Chrome reports the following on the console:
Mixed Content: The page at '
https://XXXXXXXXXXX.com/Support.do' was loaded over HTTPS, but requested an insecure script '
http://www.manageengine.com/products/support-center/scripts/scpdetails.js'. This request has been blocked; the content must be served over HTTPS.
The code should construct the URL based on the current transport protocol.
