Trouble flattening a document
I am trying to flatten a document. I am clicking on Print Production, and then Flattener Preview. The flattener Preview box opens up. I check to flatten all pages. Then an error box pops up that says "Flattening was not completed. The file was not changed." I have done this many times before and never gotten this error. I have restarted the computer and made sure my version is updated- I have adobe cloud acrobat Pro DC. Can you help please?
