Greetings. When I attempt to log in to my site, as admin, or even try to visit it as a tourist, (user) I get a blank screen except for the top where this text shows up.
Zenphoto has detected a change in your installation.
The change detected may not be critical but you should run setup at your earliest convenience.
I have been looking at the logs but I don't see anything that I can do to fix this. I have uploaded a lot to it in the last few weeks. I accessed the site as late as this morning.
Anyone see this and if so, a solution?

Now, unlike you, I still saw the rest of my gallery below the text. So, something else might be going on here.
Otherwise the message to re-run setup always triggers if the install signature of Zenphoto changes. Among things stored is the catalog of files, some core files and the general server config info. So if MySQL is updated it will trigger. It is also documented here:
http://www.zenphoto.org/news/installation-and-upgrading/#re-running-and-re-uploading-setup-files
So you need to login via yourdomain.com/admin with your master admin account and re-run setup.
However, this message should actually not be visible if you are not logged in (e.g. normal visitors). We will look into that.
Cheers.
