First, I would like to say thank you for creating this powerful plugin.
It works fine on one of my site.
But another doesn't work.
I can figure the problem occurs of using the editor named CKeditor.
It will actually add the html element <p> when write a paragraph.So,when I paste a URL from YouTube.The code will become <p>https://XXXXXxxx</p>
For some reason, I have to keep this editor plugin. And also,I have to keep writing with Visual Mode.
Can you try if you can solve this question ?
