The Events Calendar: Events page as Home page [closed]

You should be able to use the code from this answer: https://wordpress.stackexchange.com/a/96068/10

$homepage = get_page_by_title( 'Events' );

if ( $homepage )
{
    update_option( 'page_on_front', $homepage->ID );
    update_option( 'show_on_front', 'page' );
}

Haven’t tested it with multisite, but my guess is that it should work as advertised.
