I am running a free theme - Launch and I really need the Infinite Scroll feature, but I don't know how to implement it (I'm not that great with coding :()! I tried changing the num. of posts in the "General Settings" to, say, 100 posts, but the site becomes much too slow, and I don't like the "Older Posts" links.
What I have done so far is insert this code into the functions.php:
add_theme_support( 'infinite-scroll', array( 'container' => 'content', 'footer' => 'page', ) );
I'm really not sure how to get it working, been messing around for hours, doesn't work!
