Hello everyone

I think there is a problem with the flash player.
Everything was fine until couple of days ago,while all of a sudden opera stopped playing youtube videos.
For some reason,opera is redirecting Youtube.com to the mobile version m.youtube.com/? and videos are unplayable.
I've made a screenshot to show you guys how the site looks like http://prntscr.com/6ojvz3
Also oddly enough,youtube videos loaded from facebook do play,but once I click to watch the very same video, on YouTube then the problem appears.
I've tried reinstalling opera and defragmenting the disk but it didnt help.Its really annoying and frustrating.
Please help!
