So, I am building a set of simple pages for collections in an image archive. Given their requirements for discovery/browse, I have a simple page for each collection.
The install is Omeka Classic 2.7.1 on Reclaim, using the Thanks, Roy theme. I am using the Collection Tree plugin with a simple hierarchy: 2 top level collections, all others under 1 of those 2 . I am not using the Item Order plugin. I do have the Dublin Core Extended plugin.
I have the following shortcode string:
[items num=0 collection=18 sort=“Dublin Core,Title” order=a]
It displays the list of items with thumbnails just fine, but sort does not work. Is there something simple that I’m missing? The one metadata element that is always present is Title.
