Hello,

Does anyone have a hint for me?
Thank’s

As far as I remember this directory usually contains the images used by the “External sites app”, which are configured under Settings>Management>External sites>Symbols. Have you eventually played around with that app in the past?

Hello,

I have deactivate the App “External sites”. This error does not come now.
But the files in the folderare not showing.
I have read in this forum I must installed the nextcloud Dev App and look in the log file.
So I do this, and in the logfile is written:

2019-09-28 12:16:35 E Read FolderRemoteOperation
Synchronized: /"foldername" : Socket timeout exception

What can I do now?

Regards
Michael
