Joplin for Desktop 1.0.179 (prod, win32) Revision 66356d83 (HEAD)
Windows 7 Professional, Service Pack 1

I have deleted the notebook where the error occurred (in *.md).
Now another *md is marked as error.

So far the software has been running perfectly.

Many thanks for the help in advance

I experience the same error.
Has there been any solution?

@H.L.7

The error message says: Insufficient Storage
Therefore I would say that there is no more storage space available on the server.

Thank you for the hint.
I checked the WEBDAV space and there is plenty of space left.
So I reloaded the Data from the Server to the Win10 Client and it worked for a couple of hours.
But then the some error occured.
I cannnot find any reliable solution.
