If by some unknown reason IE8/9/10 are rendering your site in compatibility mode, ie IE7 mode or something lame like that, just force it to use the latest engine available:
note that the code added right before the doctype declaration. the using_ie() boolean function below (credits to Simeon for this solution: http://www.php.net/manual/en/function.get-browser.php#101314)
$u_agent = $_SERVER['HTTP_USER_AGENT'];
$ub = False;
$ub = True;
Although some of you might say this is not ethical as the user is being fooled, I DON’T GIVE A DAMN! I think it’s a great idea to have as many people as possible have this plugin installed in order to GET RID OF IE!!
You can get the Google Chrome Frame IE Update and post comments on the authors site.
