I'm fairly new to indesign and am self teaching myself via the internet and books. I'm working on a novel layout and I had it finished and what I thought looked nice. The last step was to export it to a PDF format I thought. Well, when I export it and then view the PDF a few paragraphs are broken with a few lines between the first part and second part. Chapters also lose their position. I would go back into InDesign and check and it would be that was in indesign as well. I've fixed it a dozen times. Double and triple checked the pages before hitting export again. Again, more trouble, but it would be in different places. Am I doing something wrong during the export?
Did you start this book in an earlier version if InDesign and convert it? If so, the text engine is different in the new version and stories reflow when you touch them in some way. You can force ID to recompose all stories using the Keyboard Shortcut Ctrl + Alt +/ on Windows or Cmd + Opt + / on Mac, then check carefully throughthe whole thing.
You can also force a recompose by exporting to .idml and opeing that, then saving with a new name. (See Remove minor corruption by exporting)
