Problems with InDesign display - master pages and page items
I'm about an hour from finishing a 160-page book and InDesign has suddenly thrown me two curve balls.
1. Some of my master pages are not showing up - most pages are fine. I have two masters that are simple backgrounds. Page items overlay them. The masters are applied to the pages (see image). But the master doesn't work. I have tried resetting the master on the affected pages, but it still doesn't show on the page itself.

2. I believe my other problem is related to this because it happened at the same time, but isn't always on the pages where the masters aren't showing.
Elements from my pages are missing. It's not a layer problem because each element is in the correct order in the layer. When the missing element is text, the text box is still in the document but the text doesn't show. I've made sure the ink colour is correct. The text is in the story editor, which shows that the format I applied is also still correct.
When the missing element is a photo, the box is still in the document, but the photo doesn't show.
I'm desperate for help because I need to get this back to my client.
Thanks!!
