Find in /includes/class_bbcode.php:

PHP Code:

// standard URL hyperlink
        return "<a href=\"$rightlink\" target=\"_blank\">$text</a>"; 


Replace it with:

PHP Code:

        // standard URL hyperlink
        $newtext = "<a href=\"$rightlink\" target=\"_blank\">$text</a>";
        $newtext = $this->handle_bbcode_code($newtext);
        return $newtext;
