I'm new to InDesign (working on CS6/windows). I have a "working" ID file that has a single master page that contains complex graphics (ie, I don't want to tweak it). I realized that I misaligned the page number text box and a few other items, so instead of tweaking it, I wanted to reimport that master from the original file. I copied the "correct" master from the original ID file, and added it to my "working" ID file as Master B. I then deleted the Master A, renamed the Master B to Master A, and then applied the new Master A to all the pages. Now, the master appears on TOP of the actual pages. In other words, my page content is still there, but I can't figure out how to put the master back "underneath" the page. The bottom line: how to I get my Master page to appear on the "bottom."?
If your document has more than one layer, it's possible you put the master page content on an upper layer, if not the top one.
Thanks JM! I went to my master, created a layer called "master layer" and when I went back to my page, the page content was visible, and the master "behind/below" that content layer. It did the trick!
