Thanks for your reason
That's true, when i update the platform, the list of websites were refreshed but when I put newly the list of website video providers, all rules fine.
and then...
*About Vimeo and dailymotion, in my website only one user use vimeo, and he use a password and for sure, the videos can't seeing in my website but i try to load an unlocked video and load fine (at 98% because right margin are cutted). Dailymotion there are one video upload but i can't find now, but I assume that is fine too.
With this steps, for me, it's solved. Thanks a lot.
