Votes not registering with the listener

Hello users of Bukkit, I am here to ask you a question about why my votes are not registering when I try to vote on voting websites, i.e MC-Index, and more.
I have Votifier installed, and also GAListener configured and made sure that the commands work in-game.
But when I try to vote on a website that allows me to vote for the server, they do not register in-game.
I do copy & paste the public votifier key properly, unless it's something else?
Thanks.
