I am experiencing significant issues with upload of my books to Blurb; some books appear to upload but when previewed in Blurb some photos are missing (all the pages are there) and other books fails to upload with a generic error message in Lightroom. I have published through Blurb before and so I know that the system can work. I have also tested that Lightroom can publish to pdf. The problem existed in the previous version and continues in the latest version which I have just downloaded. Can anyone help?
