hello, im getting these errors on my javascript console and im not sure if its an issue..every thing seems to be working fine except for the fact that i had to switch over from frondend editing to creating content from the admin panel on k2 backend admin becuase it would not show images images/video/audio after saving..

could you tell me what it means and how i can resolve..thanks

'HTMLVideoElement.webkitSupportsFullscreen' is deprecated. Its value is true if the video is loaded.

This is unrelated to K2. A chrome extension is causing this.
