Error: Unable to create dir: /srv/www/htdocs/gallery_neu/albums/.usersUpgrading Users
The user database in your gallery was created with an older version of the software and is out of date.
This is not a problem!
We will upgrade it. This may take some time.
Your data will not be harmed in any way by this process.
Rest assured, that if this process takes a long time now, it's going to make your gallery run more efficiently in the future.
If you get an error, and only some users are upgraded, try refreshing the page to upgrade remaining users.
