I can fix it by removing the Youtube plugin from the forums. That seems to be the only solution. Chrome is getting rid of Flash support so they are warning people whenever anything Flash based is wanting to be played.
As Youtube was flash based, for a million years, all the plugins had to deal with it.
It is a browser issue (Chrome, specifically), but it seems the only way to deal with it is to remove that plugin. I hate how we always have to capitulate to Google.
