I am using version 1.1.3. I have uploaded 35 images in 6 albums. When I am in the Admin-mode I see the 6 albums on the Index page, but if I am in the visitor mode I see only 4 albums on the Index page. It does not seem to be a cache problem for I have tried this on other computers.

How to repair this ? I would be very grateful for a quick answer.

Check in the admin if you really have set all your albums to published. The admin sees them all, normal visitors don't.

That was the solution of the problem. Thanks a lot !
