I reverted back to 1.5 because for me it was working better. fixed the no stip in quote bug. all the options variables were wrong
Goldbrick: Filter Goldbrick BBCode in Quote Tags Part 1 & 2
should be
Code:
if($vbulletin->options['gb_enabled'] && $vbulletin->options['gb_filter_quote']) {
$pagetext = preg_replace('#\[(/?)' . $vbulletin->options['gbtag'] . '.*\]#siU', '[\1url]', $pagetext);
}
this fixed it. It's possible that's all that's needed for 1.8 too but I didn't test it
