Digikam does not show any thumbnails

I installed digikam on a new computer and copied the database and some of the photos from the old computer. Then I added new raw photos.

In the preview view, there are no thumbnail previews visible. After doubleklick on a single photo, the detailed photo is shown perfectly.

I tried on selected photos (original language is German):

  • Update (F5)
  • Menu Extras / Maintenance / Create new thumbnails

Nothing helped.

Has anyone proposals what could be done?

can you get some logs and tell us what they say?

Have you tried toggling “Settings → Show Thumbbar”?

Harri

I will be glad to provide logs, but am not sure how to do this.

I tried toggling this in the image view, but with no help.

Here are some logs of warning level from the current session, but Digikam GUI does signal any error like locked database.:

are you using sqlite or mysql?

SQLite. No backgound process is running.

Today only three new log lines, no database lock:
