Not exactly the answer to my question, but I found a way to get the social icons in the footer.
For future reference:
In header.php <?php do_action( 'poseidon_header_bar' ); ?> is what displays the top bar menu and social icons in the top header (above the main header). The top header bar is part of Poseidon Pro. After installing the Poseidon Pro plugin you can find the code for the header bar in includes/modules/class-header-bar.php.
I moved <?php do_action( 'poseidon_header_bar' ); ?> from header.php to footer.php and then used CSS to make it fit in with the rest of the footer.

Same problem here. Most recent update (3.0). After a recent plugin update the website froze.
