JWPlayer (new version) throws an error and doesn't play on the site

Question

I am using latest version of JWPlayer and it shows a blank space when open the page with the video. The weird part is that when I refresh it twice/thrice, it works fine.

But it almost never works the first time the page opens.

This the error it shows in the console :-

Error handling "jwplayerReady" event listener [0]: SyntaxError: Failed to execute

 height: 52px; margin-top: -26px; }'. function (b){l.playerReady(b);a.css.unblock(d.id)} 

Any idea why this is happening?

Thanks.

Answer 1

In my case, it happens when my container div ID starts with a numerical character.

jwplayer("2someID").setup({
        file: fileURL,
        image: imgURL
    });     

see my example in this jsFiddle
try changing the div container id with a non-numeric character.
