OMV7, WebDAV plugin up and running, folder to be shared indeed listed in the Shared Folders menu, all permissions given.
When accessing the "ip.address.of.webdav/webdav" with a browser (tried Chrome, Edge and Arc), I can see the contents list of the designated folder. However, after clicking anything (foldes or files), I get an red error message: "Software Failure. Press left mouse button to continue. The requested page was not found".
After clicking with the instructed left mouse button, I get to the OMV7 login page.
Any help?
