The <iframe> tag fails to work in my posts whenever I try to use it, making it impossible for me to embed YouTube videos and whatever else the tag allows one to do. This doesn't seem to be the case for other users and I don't see any reason why I would happen to be the person it doesn't work for. If there's anything anybody can do about this or if you could suggest a solution if the problem is on my side, I would be thankful.
