Infinite scrool support request

Hello,

I got in contact with my theme’s developer. He said I should add the following to the functions.php

add_theme_support( 'infinite-scroll', array(
    'container'  => 'middle_single',
    'footer'     => 'footer-bottom',
) );

However it doesn’t work even though I added that and the infinite scroll is enabled in the settings . Could you please take a look at glamourina.pl?

Thanks
