Adding another user who’s having an issue here. We use Tags for visibility and it’s no longer working. The Tags in download manager no longer seem to be tied to the tags list in Posts.
Did you ever get help with this/figure out how to resolve this? I’m working with the same thing right now.
I’ve done a little more digging in the forum, and saw this link: https://www.wpdownloadmanager.com/using-upload_mimes-to-allow-upload-and-download-of-unrecognized-mime-type/. We have a different plugin that supports the extra file types, “extra file types”. But the file I’m downloading is a zip file, so it’s a standard, supported file type. So, little stumped.
