WEBDAV: Cannot modify files

ℹ️ Support
1

Nextcloud version 24.0.6
Operating system and version: Ubuntu 22.04
Apache version: Apache 2.4.54
PHP version : 8.1.11

The issue you are facing:

I connect to my data on Nextcloud from Windows 10 using WebDAV. Creating new files, deleting, copying and pasting under a different name is no problem.
I can do everything with my files except modify an existing one.
For example, if I open an Excel file, change numbers, and then click Save, I get: The document was not saved.

The same effect is also visible via the Nextcloud client. The changed file is simply no longer synchronized.

Is this the first time you’ve seen this error? : Yes. After i Updated Nextcloud from 23 to 24

Steps to replicate it:

  1. Open WebDav under Windows
  2. Open a File and make changes
  3. Try to save the file

The error was already with ubuntu 20.04 and PHP 7.4. I then made the upgrade to Ubuntu 22.04 and php 8.1.11 in the hope that it then works.

Thanks for any help

I’m having the same issue when nextcloud apps (such as drawio or the text/markdown editor) try to modify files. Creating new files is not an issue, only modifying existing ones.

Having the same issue here. Maybe any update on this?

Edit: Updated the files_versions app manually to 1.18.0 and seems to works now.
