Gtranslate (on the fly) works fine with Firefox and Chrome.
However it doesn't work with IE 11.
Firebug explains why :
SEC7118: Voor XMLHttpRequest voor http://translate.googleapis.com/transla ... c=2&mode=1 is CORS (Cross Origin Resource Sharing) vereist.
CORS functionality is required. This needs some adjustments at (your) server side i guess.
Changing browser security settings doesn't solve the issue. Maybe i didn't change the right ones.
Maybe you can add a solution (if any) to your FAQ answer (why clicking on the flag doesn't show anything).
