The HTTPS Everywhere rule for ning.com (partial) causes images to be missing from ning-hosted websites, e.g. DiyDrones.com . Note: The actual version is HTTPS-E chrome 2014.4.16 . Defect is due to an invalid certificate on Ning's CDN. This is the communication I had with Ning: Apr 22 12:46 PM The SSL certificate for https://origin-api.ning.com is invalid. It does not match the URL, it is expired, and it does not have a valid CA. The certificate for https://www.ning.com is valid and would also work for origin-api.ning.com. You should install it to all your servers. Aaron (Ning Help Center) Apr 23 05:20 PM Hi there, Thanks for your question! We don't support SSL on that URL. That serves up our images via our CDN, which is also not currently set up for SSL. Best, Aaron
