The object place holder is a tinymce config issue, and it is a pain to fix manually. I had to fix it by editing…. post.php in wp-admin/ …. I THINK! I’ll run a file compare in the morning and update. [apologies, can’t do the file compare on my iPad. 😉 ]
I installed the Vipers Video Quicktags plugin just to try if I could see any videobox in my editor, but still no yellow box. Before I updated WordPress there always was a yellow flashbox. Can someone help??!!
