Language Sensitive Footer

What do you mean by language sensitive footer.
Your are working with polylang to have different languages on your page.

You can activate shortcode support of polylang via your functions.php of your child theme

function polylang_shortcode($atts, $content = null)
{
	if (empty($content))
		return '';
	extract( shortcode_atts( array('lang' => ''), $atts ) );
	if (empty($lang))
		return "<h3>You must specify 'lang' using shortcode: polylang</h3>";

	return ($lang == pll_current_language()) ? $content : '';
}
add_shortcode('polylang', 'polylang_shortcode');

from that time on you can edit different languages in Enfold input text fields like:
[polylang lang="en"]Whatever you like here[/polylang][polylang lang="de"]what ever in german[/polylang]

the[nolink] is a different shortcode which disable footer notice to kriesi source of the theme.
you see here what i mean –

[polylang lang="de"]
