Rispondi a: How to add multiple quality video

Hello,

Thanks for your reply. But sorry I can not see that. I purchase from codecanyon and paste the purchased code from codecanyon and paste to the “Premium Key” field on plugin setting. Is it right?

And when I edit the post, the option of plugin just like this screenshot bellow. No more source field. Please look:

Am I wrong with the premium key? how to get the premium key when I purchase from codecanyon?

Thanks
