bhaldie on "[Plugin: Memphis Documents Library] Not Authorized to View File"

I'm having an issue with some files, seemingly random, where I get a "you are unauthorized to download this file" error.

This occurs on all user roles.

I am unable to identify any difference between the files that are throwing that error, and the ones that are not.

Please advise.

can you tell me the setting you have for the files giving you the issues, for example hidden or Public etc.

The settings are
- Public
- Published
- downloadable by non members (checked)

does preview work on the selected files.
