OK – solved it:
For anyone that needs to do this:
Go to shortcodes.php
and replace the Tooltip shortcode with this:
/* TOOLTIP SHORTCODE
================================================= */
function sf_tooltip($atts, $content = null) {
extract(shortcode_atts(array(
"title" => '',
"link" => '#',
"direction" => 'top'
), $atts));
$tooltip_output = '<a href="'.$link.'" target=\"_blank\" rel="tooltip" data-original-title="'.$title.'" data-placement="'.$direction.'">'.do_shortcode($content).'</a>';
return $tooltip_output;
}
add_shortcode('sf_tooltip', 'sf_tooltip');
