I try to setup D7 + ckeditor 4.3.x in conjunction with wysiwyg + media (v1) modules.
Everything is ok for text edition and image insertion with the media browser button in ckeditor.
The problem is: I try to add the media_youtube plugin and videos do not show in content. Instead I have a placeholder.
Downgraded to ckeditor 3.6 and everything worked perfectly again.
But I'd like to keep the new features in the newer version of ckeditor.
Any idea what the problem could be?
