Good day.

It is happening because variable $_SERVER['QUERY_STRING'] contains
&lang and You want add next in Your script. You must filter it. You can
use this (footer.php):
<?php
$new_qs = preg_replace("/(.*&?lang=)(?:.*?(&.*)|(?:.*))/",
"\\1".$toggle."\\2", $_SERVER['QUERY_STRING']);

echo '<a
href="http://website.com/'.$_SERVER['SCRIPT_NAME'].'?'.$new_qs.'">'.MENU_TOGGLE.'</a>';
?>
