Hello,

I recently took over the creation of my company's general catalog (300 pages), which I had previously entrusted to another graphic designer, who transferred the file to me. Since I've taken over the design of the catalog, I've run into a lot of different problems:

Sometimes, entire pages disappear. Sometimes, text and images are preserved and visible when I'm in “W”, but the background of the blank page is no longer visible. As a result, when I'm no longer in “W”, the page disappears completely.

Also, sometimes images disappear, for no reason at all, or strange shapes appear next to my document.

I've tried :
- Copy and paste the disappearing pages into a new Indesign, that works.
- I've gone looking for pages from our old catalog that I've put in the file that bugs, and these same pages end up having the same problem. (elements disappear...)
- I've saved the file in an IDML and it works, only when I export it as a PDF, the initial problem persists.
- I'm in the process of separating each chapter of our scale into separate Indesigns, let's see if it works

Do you have any idea why these pages are disappearing?

Ps: I'm on Windows
Indesign Versions : V19.5

Attached is an example of the problem I am experiencing

I need your help as soon as possible!

Thank you in advance
