I changed the size of this document in Document Setup to 51p0 x 66p0 for print. Whenever I export it to PDF, the PDF gets cut off by a couple of inches at the top, whether I view it in Acrobat Pro or Reader. I created this document in the latest version of InDesign, and I have the latest versions of Acrobat/Reader installed too. What do I have to do to export the document in its full size without anything being cut off?
I had this to in some documents. You can try to copy the layout and paste it into a new InDesign document with the 51p0 x 66p0 format. Look if it's then ok.
