I use Shadowbox 3.03 and untill lately the &fs=1 parameter for embedded youtubes worked fine.
All of an sudden it stopped. I do see the fullscreen option but it says that 'fullscreen is unavaillable'. I have tried it in several browsers and two laptops.
However, fullscreen should be enabled by default but it does not work when the embedded yt is opened in Shadowbox-js.
Is this a Shadobox issue or is yt to blame... or is it me and my terrible programming skills :(
