It is no longer possible to change my PNG or JPG logo

Leo, something went wrong, after you asked to disable all plugins to see where the problem was, and I turned all plugins back on, my images are no longer loading, see my attachment pages> for example> https://www.davidbowieworld.nl/mijn-bootlegs-2-2/bbc/attachment/david-bowie-occasional-dreaming-27460-copy/#main

I'm not seeing the issue on my end:

You might need to try disabling all plugins again to eliminate any conflicts if you are still seeing the issue.

try this one https://www.davidbowieworld.nl/mijn-bootlegs-2-2/bbc/attachment/david-bowie-occasional-dreaming-27460-copy/#main

and many more

The theme itself doesn't have the ability to prevent your images from loading so the conflict is likely coming from elsewhere.

you have to scroll down

Have you tried disabling all plugins again?

Please open a new topic if you are still experiencing the issue after all plugins are disabled.

I'll mark this one related to the logo as resolved now.

Thank you.

ok , thanks Leo

No problem :)
