I changed several pages with page manager, front page, nodes...
But there is a particular page where ajax login don't work. It pops up fine but when clicking on enter it just refreshes the pop up window.
You can check it here: http://www.natate.org/proyectos-de-voluntariado
The same page in english works fine: http://www.natate.org/en/proyectos-de-voluntariado

Do you have any idea what can be the issue?
Thank you
