Hi there @steklosvetlana,
I’m not sure what made this issue occur on your site, as I have tested countless times for such issues but there weren’t simply any maybe I missed something.
I would love to look into this for you, if you could provide a bit of information on that error.
Also, I’d want to you to try the newer 0.5.0 version available now, which includes a lot of new changes and improvements. Such as Youtube, Dailymotion & Vimeo video embeds.
Hope this helps!
