Over night, Plex has decided that it can't see any of my library files for movies and TV shows. They were fine before, they have been for years. Only music is unaffected.

I get a message saying "movies is empty. Expecting more? Visit the manage libraries page"

I've tried creating a new library pointing to the same directory, but that one shows the same error in the end.

Had a look on the forums, but not found anything relevant
