Not working

Thanks for your interest in the plugin and for your question. Without seeing the source text of the shortcode you have added to your page, I can only give you some general advice.

A good place to start is a simple shortcode that displays some of your PDF documents:

[mla_gallery post_parent=all post_mime_type=application/pdf link=file numberposts=20]

In this shortcode:

• post_parent=all – select all items, not just those attached to the current post/page
• post_mime_type=application/pdf – select PDF documents (the default is images)
• link=file – go directly to the document when you click on a thumbnail, not to the “attachment page” for the item
• numberposts=20 – show the first 20 items (in case you have hundreds in your Media Library)

Your wrote “added media files (PDFs >1MB) to categories“. If you mean the MLA “Att. Categories” taxonomy, you can replace the post_parent=all parameter with something like attachment_category=some-category-slug. If you mean the WordPress “Categories” taxonomy, you can use something like category_name=some-slug (the WordPress paremeter name) or category=some-slug (MLA synonym for category_name. Make sure you are using the correct slug/name value for the term, not the title value; this can be confusing.

I hope that helps get you the results you want. I will leave this topic unresolved for now; any additional information you can give me will let me be more specifically helpful.
