If you're really stuck, you can email hello@leanpub.com and we'll try to help.

But before you do that, can you try this?

  1. Go to https://leanpub.com/YOURBOOK/versions
  2. Download an archive of the most recent success and most recent failure.
  3. Try replacing the manuscript with the most recent success and preview again, as a sanity check.
  4. Assuming it works, replace the manuscript with the most recent failure and preview again, as a sanity check to ensure it still fails.
  5. Compare the two manuscript directories (using diff, if you're a programmer) and see if anything jumps out.
