I have a short document, just 11 pages. Pages 6&7 for some odd reason are bumped to the right, and it's messing up the header on page 6. (The header is appearing on the right side instead of the left side.)
Both pages are on the same side of the spine. Look in the pallet menu, and make sure that Allow Document Pages to Shuffle and Allow Spread Pages to Shuffle are checked. If they are unchecked, checking them should fix this.
Does it help to export as IDML, open this and save as new file?
Beautiful. Thank you very much, SRiegel.
