Resharing impossible

Nextcloud version (eg, 18.0.2): 18.0.4
Operating system and version (eg, Ubuntu 20.04): Debian Buster 10
Apache or nginx version (eg, Apache 2.4.25): 2.4.38-3
PHP version (eg, 7.1): 7.4.6-1

Since a few months, I share a folder with my wife, with all the permissions. She can reshare, edit, create, delete, etc.
Since today, she can’t create resharing link anymore, she can just share her files. I don’t know why, it worked like a charm since a while…

Perhaps it is the same problem in a simmilar discussion from today. Sorry link lost.

Did this start after updating something?

Can you post a picture of the error?

Ok, I found, a button was not checked, but, it’s weird, I have never checked this button… Must be a new option…


Thank you !
