I cannot share a folder or file with a person, not being registered as user.
When I compare the related illustrations in the manual with the screen, I missing the “copy link” and the “share menu” button right to the blue “share link” icon on the left side of the right side menu

Nextcloud version 15.0.2
Operating system and version Linux Mint 17.3
Apache or nginx version _unknown

The Nextcloud 15 software has been declared “end-of-life” in December 2019.
Please update you installation asap to a supported Nextcloud version, e.g. v20. Many functional and security related issues have already been fixed in newer versions, the described one seems to be one of these.
Thanks for your hint with blockers. I have uBlock Origin running. In this case I need to switch of uBlock Origin completely. Allowing all NC related sripts did not work. This I could test and verify before the Upgrade.
On my new Linux Mint 20 installation there is no Problem with uBlock Origin.
