Hi all,
The mime_content_type function wasn’t deprecated, then it was, now it isn’t again.
The good news is that PKP software only uses it as a fallback when the “preferred” mechanism, the fileinfo suite of tools, isn’t available. See Error message on upload: "No file uploaded or invalid file type!" for more information about how OJS/OMP/etc. determine file types.
