This Add-on has a serious bug:
The Code on Hook bbcode_parse_complete assumes that
PHP Code:
$this->bbcode_tag_list
does always exist, which is not necessarily the case if do_parse() is being called directly (PhotoPost vBGallery for example does that).
So this causes the Tag-List to become empty after the first call to do_parse().
Changing the code it
PHP Code:
if (isset($this->bbcode_tag_list))
{
$this->tag_list = $this->bbcode_tag_list;
}
