Login buttom doent pop up the window even with joomla doesnt connect

Hi, i just have the form of joomla and the connect with facebook buttom, it doesnt connect with the buttom, even when i connect with joomla's form and the appears the blue buttom that says connect, i click and nothing happend, even the pop up windows doesnt appear!!!, but the window for comments works really fine, i have in the bottom of my page the comment area and it logins with my picture and everything, but seems that it's not connect with the login buttom 'cause show me that it's not connect...

Any ideas? I already changed the order of the plugins that you mention about authentification -100 and the other one... am i doing something wrong in the configuration?

Thanks
