Shares broken after upgrade from latest 27 to latest 28

After upgrade from latest 27 to 28.3 the shares does not work anymore - when i click something in “Shared with others” or “Shared with you” the link brings me not into the shared folder - but in the subfolder direct under the shared one…

Maybe only the links are wrong. Please test https://cloud.server.tld/apps/files/sharingout.

On my setup for example under “Shared with others” links look like
“domain/remote.php/dav/files/USERNAME/SHAREPATH/SHAREDFOLDERNAM”

And this always goes into root of the the files of the user…

You must differ between links to person in Nextcloud and public link. You link is a link shared to a person in Nextcloud and not a public link. A public link is https://cloud.sever.tld/s/abcdefghijklmno But i thought the list is wrong. And with my link you can get the list of shared links. Please post a screenshot. Also you can use browser dev tools (F12) to find errors. Post them.

This “/index.php/apps/files/sharingout” is working - its the same as when i go into “Shared with others”
And there see all my shares - but when i click on something there is a strange behavior - example:

Example…

on Mouseofer of one of this shares it says
URL/index.php/apps/remote.php/dav/files/USERNAME/privat/Memorial-Event

when i click on it it goes to
URL/index.php/apps/files/files/495306?dir=/privat

  • i am one folder under the shared one…

when i know push F5 go back in browser my sharing out is empty and the link looks like this:
/index.php/apps/files/sharingout/495306?dir=/USERNAME

and when i here click again F5 i am in the shared folder…

but the folder looks strange too - there are spaces in the pathnames - at leas it looks like that - maybe there should be some icons…

Side-question - i want to go back - i have the latest working 27 nextcloud folder and the DB at that time saved but not the data-folder - when i want to go back do i have to do something with the data folder too?
