You probably need to enable the files_sharing App and make sure that "Allow apps to use the Share API" in your admin backend is enabled.

When enabling files_sharing : ask me to upgrade

doing that

all check ok
integrity code check : ok

Always can't share calendars ...

Make also sure that you're not using IE11/Edge and also see this suggestion:

all is correct now

php occ upgrade done

all check

All is clean now.


ps : how can i close feed ?
