If you “Edit” the galley, what do you see in the “File Type” section?

Many thanks,

That seems like a good configuration. I tried uploading an XML file to 2.4.8-2. It was identified as “application/xml” and it downloaded as expected.
I see you are using OJS 2.4.3.0. Are you using any special plugins or local customization?
Dear @ctgraham
We used from PubMed XML Export Plugin.

Do you have other articles where you are publishing NLM XML and it is displaying correctly? If so, is this particular article valid NLM? If not, you might want to disable this plugin to make the XML downloadable throughout your journal.
