Adding a link to the footer

Hi, in the footer I want to add a link for the GDPR. So I tried to change my functions.php in the child theme:

Copy the line with disclaimer and replace the link to my new page, results in a error 500.
Just copy this line, is showing two links to the disclaimer in the footer, but changing it leads to a blank website.
Adding the code between ‘ ‘ behind new_line credits, isn’t showing the link.

I want to add this link:
<a href="http://www.farcows.nl/privacyverklaring/“>Privacy</a>

And I have this code:

// Adding a disclaimer in the footer before credits.
add_filter('tc_credits_display', 'my_custom_credits', 20);
function my_custom_credits(){ 
$credits = '';
$newline_credits = '';
return '<div class="span6 credits"><p> &middot; &copy; '.esc_attr( date( 'Y' ) ).
' <a href="'.esc_url( home_url() ).'" title="'.esc_attr(get_bloginfo()).
'" rel="bookmark">'.esc_attr(get_bloginfo()).'</a> &middot; '.
 '<span class="tc-credit-text"><a href="http://www.farcows.nl/disclaimer/">Disclaimer</a></span> &middot; '.
($credits ? $credits : 'Designed by <a href="http://www.presscustomizr.com/">Press Customizr</a>').' &middot;'.
($newline_credits ? '<br />&middot; '.$newline_credits.' &middot;' : '').
'	 <span class="tc-wp-powered-text">Powered by <a class="icon-wordpress" target="_blank" href="https://wordpress.org" ></a></span> &middot;</p>		</div>';
}

What am I doing wrong, help?
And is there something else wrong with the footer, because I’m not getting images anymore …
