Change footer credits?

Hi, you have to do it in the php code. Specifically the footer.php file. Or you can add a function to functions.php to override it. Like this:

/*
 * Override site credits to say "copyright [year] by [sitename]"
 */
add_filter('xsbf_credits', 'xsbf_xs_credits');
function xsbf_xs_credits ( $site_credits ) {

	$site_credits = sprintf( __( '© %1$s by %2$s', 'xtremelysocial' ),
		date ( 'Y' ),
		'<a href="' . esc_url( home_url( '/' ) ) . '" rel="home">' . get_bloginfo( 'name' ) . '</a>'
	);
	return $site_credits;
}
