Hi Frank.
So here are my responses:
1. Message Type not showing up. Not sure what is happening to you. If you look at my church site it does show up.
2. When I unpublish a study it does not show up on my list.
3. Ordering. So there is a bug in one of the views that doesn't allow the ordering to work. What you'll need to do is edit this file:
/administrator/components/com_biblestudy/views/mediafileslist/tmpl/default.php. On line 79 there is a mispelling of saveorder. Make it like this:
echo JHtml::_('grid.order', $this->items, 'filesave.png', 'mediafileslist.saveorder');
What I had to do was filter the study title so I had only the media files from a particular study in the list. Then I clicked on the Order header, that activates the boxes where you can enter a new order then click the disk icon to save it.
What's your url so I can see this happening - and what study did you delete and now shows up?
