Hi,
That's a link of the upload system for custom fields.
They should not be indexed.
Change the code:
$html = '<a '.$a.$onClick.' id="'.$id.'" href="'.$url.'" data-hk-popup="squeezebox" data-squeezebox="{title:\''.$title.'\',size:{x:'.$params['width'].',y:'.$params['height'].'}}">';
} else {
$html = '<a '.$a.$onClick.' id="'.$id.'" href="'.$url.'" data-hk-popup="squeezebox" data-squeezebox="{handler: \'iframe\', size: {x: '.$params['width'].', y: '.$params['height'].'}}">';
to:
$html = '<a rel="nofollow" '.$a.$onClick.' id="'.$id.'" href="'.$url.'" data-hk-popup="squeezebox" data-squeezebox="{title:\''.$title.'\',size:{x:'.$params['width'].',y:'.$params['height'].'}}">';
} else {
$html = '<a rel="nofollow" '.$a.$onClick.' id="'.$id.'" href="'.$url.'" data-hk-popup="squeezebox" data-squeezebox="{handler: \'iframe\', size: {x: '.$params['width'].', y: '.$params['height'].'}}">';
in the file administrator/components/com_hikashop/helpers/popup.php and that will prevent search engines to index them next time they index the product pages on your website (it might take a while).
