Hello, when I upload a video via direct link from youtub, it is added in a huge way. Something in XenForo, which I show in the pictures, supports several sites. It is added in a small way as shown in the picture.
In our case, HTML needs to be activated in the easiest way and there is a warning like unsafe html. Of course, it would be annoying and a simpler way.
In our case, I added pictures showing how it happened and how it looked.
I used 5.3 RC 1 as version.
