Said webpage: http://www.portugalpoker.net/
All major browsers open and render this website. I've tested it on Windows and OSX with IE, Firefox, Safari and Chrome.
Chrome loads the webpage (you can see the source and it also fetches all javascript and css files), but doesn't display it.
Did I code anything wrong?
That is weird! It does load the source, however, when you look at it with the Dev Tools, all you have is
<html>
<head>...</head>
<style>...{ visibility:hidden !important; display:none !important; }</style>
</html>
And in the Resources tab you have "Failed to load resource"
So I'd start by looking at that!
