Re: tinymce showing two textareas
@ crashfirephoenix: I got the same problem. I deactivate some plugins and the problem was fixed.
If you got the same plugins that I had installed, try deactivate them.
They are: BBcode Buttons Toolbar, BBcode lite, Live Comment Preview.
And if you got the TinyMCE as editor, you don’t need any of them, right?
Let me know if it helped.
