I cut some pages, and now all of a sudden my entire 300 page document is strewn with gray lines messing up my page lengths. How do I get rid of those lines and get back to actual pages again?
How do you expect to get an answer without providing any technical details? Minilmum is OS and LO version. Edit your question to attach a screenshot and, better, a short sample file. Note you can’t attach a file to a comment; you must do that in your question.
