Pas glop : can't see my pictures

I can’t see the images in my directories.
This works with version 5.8, but not with 5.9, which I’ve just installed/uninstalled/reinstalled.

Linux Mint, last release , RT 5.9 (last)

Have you checked the settings to ensure the file extensions of your camera are enabled?

Well done!
Thank you so much…
I’ve gone through the “browser” section a thousand times but never looked there.
It has to be said that until now I’ve never had this problem with previous versions.
