I'm having an issue. When I click on a link to download a book, I get a blank page with only "No input file specified."
I have all files set to 777 permissions
WHat I am thinking (but not sure how you or Calibre does this) is that I have all the books in subfolders (ie: Author/Book/Book.mobi) which was configure per Calibre in Windows. I copied the files exactly as they were on my desktop machine and the metadata.db as well.
