I have reported the issue to Google Chrome but if you are having the same issue, then please report it to them by clicking on the box at the top right and going to Help and then reporting it. Firefox works fine.
The issue I see is that youtube videos are only showing up as black boxes instead of videos. I am having the same issue on another forum that I am on that uses a different software and a member there also reported having the same issue and others chimed in too, so it is a known issue.
Just letting you all know that it is not the forum, it is Google Chrome since the last update they did.
