Results in "An unknown error has occurred" popup in the upper-right. But a refresh shows the file was uploaded correctly. Getting reports from clients they are having issues, but of course we are still getting the files.

massa007 commented 4 years ago

Disable the Activity App - this solves the issue for UPLOADING files for now. But I still have the issue that I get the same error while trying to change/delete a file on a shared link. I don´t have a workaround for that. Anyone else with the same problem?

krocheck commented 4 years ago

Confirmed, disabling the Activity app as a workaround clears this up.

majesty54 commented 4 years ago

not really the same for me :

I can upload without any errors

Indeed:

I can't delete any files
I can't rename any file

Activity App already disabled without success

majesty54 commented 4 years ago

After upgrade to 18.0.4 I can now rename a file! But still can't delete any file on the public share.

kaoschris commented 4 years ago

NC Version 18.04

We can't delete any files
We can't rename any file

As I cannot reproduce the original issue anymore, I will close this ticket. If this is still happening please make sure to upgrade to the latest version. After that, feel free to reopen. The latest version can be seen by checking https://nextcloud.com/install/#install-clients and https://nextcloud.com/install/#instructions-server respectively.
