when I insert some html code into the 'html' tab within a 'new post' and I switch back to 'visual', the 'yellow box' which previews the size and position of the code (video, soundcloud player etc) doesn't appear. However, when I preview post - said video is there.
I need to have access to the yellow box to resize the media.
Any advice would be great.
P.s My site was down to day with a 'fatal error' message due to the wordpress update - not happy.
