Hello, i will test the zenphoto 1.5 and have problems.
The first problem is, the setup is only in language german. whit querystring ?locale=whatever there is only blank pages.
The next problem is the "create database", it's not work. The zenphoto.cfg.php was updated, but the database not created. "Unknown database '...'".
PHP 7.

I am sorry, I don't understand the setup in German issue and what querystring you are referring to. There is a small issue with a constant for the protocol not correctly defined in setup. Maybe that is what you encounter.

Zenphoto can only create a database if your server allows to create it. Probably your's as the majority of hosts does not allow it. You need to create it yourseflf beforehand. This is neither new nor has this been changed.

via the command line i can create databases. I also do not know that it would be forbidden by PHP. It is not a major host service. It's a hoster for selfprogramming people.

In the setup-page in the footer are flags for languages wich create URL querystring, but by clicking, only a blank page is open. Standard is german and works.

On blank pages the first you should do is review your PHP error log. What does it say?

The notice is the issue we already know about. The 2nd one is permissions you (or your host) probably need to try to fix.
