Cannot display or output spread / facing pages
I am working on a 20 page 4/4 bleed report set up in the indvidual page mode. At one time during the process, I switched over to the "facing pages" mode and exported a pdf to review my work. Then I went back to work on the file and switched it back to the page-by-page display mode.
Now, when I attempt to switch the display over to the "facing pages" mode, InDesign ignores the command and remains in the page-by-page mode. Similarly, when exporting, I select "spreads," and Acrobat exports the file as pages.
I suppose somewhere, somehow, I managed to contaminate the ability to display spreads but do not have a clue what I did.
Can anyone help?
Thanks to those who know more than me,
Joe
