I have searched older post with keywords "configuration file", setup file, zenphoto configuration, but found nothing, sorry.

I created a new zenphoto website, copied from my current Zenphoto. I am missing the configuration file where it says how many images per page, etc. In fact, everything that we can edit in the admin page. Where could I copy this file from?

Thanks.

You probably have a really old Zenphoto then. Those things like images per page are backend options for way over two years now.

Maybe you should visit our site, look at installation instructions and view some screenshots? Looks like it's time to upgrade...;-)

Oh no!!

Last time I tried to update I lost plenty of stuff.. Will it be able to convert all those settings If I upgrade? Because my original site is 100% fonctionning and is exactly what I want, I'm afraid to screw it up ;(.

If you tell me it should convert everything flawlessly, I'll upgrade!

Well, since you have not identified the version of Zenphoto you are running we can only speculate from your description of the settings.

This would indicate an ancient version prior the the v1.1 release of November 2007. As such, it is unlikely that there would be a smooth upgrade path.

On the other hand you can hardly expect us to be able to help you with this level of software.

We would really suggest you make a test installation and see how difficult it would be for you to migrate your gallery.
