I have a website which is accessed via https (and all resources are loaded via https too), where I have a Nivo Lightbox which should show a Youtube video (as an overlay over the website). The JavaScript libraries I use (jquery and nivo-lightbox) are both stored on our server and referenced directly. Unfortunately, I get a Mixed Content error in the browser. It says that the YouTube-video (referenced with https) is from an insecured resource (so not https) and is therefore has been blocked.
I tried various things to overcome this problem, e.g. by removing "https:" and just having "//youtube.com/..."; but couldn't solve the problem or other people who still couldn't solve the issue...
Does anyone have a similar problem and/or a solution? Any help would be very much appreciated.
