Greetings Gilles,
On a new installation: Digikam comes up with Albums and below that Pictures, listing all the folders in the database, but then, when you try to open a Folder to access the pictures the Folder is blank! (nothing shows up).
Therefore I tried going in the settings, migration; to no effect. Tried settings, Configure Digikam, add collections and again no result. I have experienced this in the past and after a lot of fiddling managed to get the pictures appearing, but not this time. Have tried with "Permissions" on the HDD in case they were set as root instead of the user (myself) and that showed OK.
Your help will be greatly appreciated.
TIA
