I would appreciate advice on the following problems I have encountered. After uploading in the last 2 months 5 books to Blurb, I suddenly ran into a problem with one book. In the process of uploading I got an error message that there was an error with the book and the details below said error because of adding text and fonts. Originally I did not know were to begin. Checked all the fonts of all the text pages and made sure only ONE font was used (Book Antiqua). I checked all the page numbering and all the captions. None to this helped to upload my newest book.
Thanks to the Community I then found out that one should first export a book to PDF and when clicking on the progress bar one can detect where the problem occurs, I did this and found out the process of exporting my book to PDF stopped at about page 25. I checked that page, it had no text and had no fonts. I thought that maybe the single image was the problem and I changed the image. This made no difference: exporting stopped after a few pages wee loaded.
Today I went back to all my earlier books and exported each book to PDF. All of those exports worked fine.
Can you please help me to figure out how come I cannot export my newest book to PDF, nor can i upload it to Blurb.
Please don’t send me to Blurb because it is not their responsibility to maintain and upgrade Blurb in LR!
