Hi Mac (or onyone else who may be having this issue).
I also ran into this with this module on the first template I tried to add it to. If course, this is a template that I wouldn't normally use, so that just adds confusion, but I found that when I simply switched the template, the issue corrected.
So, I looked that the line of code it was complaining about and I see that it is asking the template for the language direction (Left to Right or Right to Left (ltr or rtl)) - I figure that this particular template doesn't have this feature/variable advertised in it, so it doesn't work. So I took out the line and set the language to ltr, which is all it would ever be here.
The old code looked like this
$document =& JFactory::getDocument();
$app_direction = $document->params->get('direction', 'ltr');
$params->set('direction', $app_direction);
and the new code, looks like this:
$document =& JFactory::getDocument();
$params->set('direction', 'ltr');
I hope that this helps someone else eliminate this error while using this plugin. I haven't even implemented it and I've adde to their community!
