I activated the default theme and still cannot enable the core slideshow. I still get the black screen when I click apply.

I am using the "latest" version of Zenphoto supplied by my hosting service. While I know there are later versions of Zenphoto, I have not found a way to upgrade the installation on my host's server.

Thanks for all the help. I really do appreciate it.

Manual installation is not that difficult see our install page. A blank screen should result in an error in the log somehwere.

But in any case you should inform your host that it upgrade the script!

Thanks. I will definitely notify my host and request that they update to the most current version. At the same time, I will look into manually installing the latest version.

Manually updating Zenphoto to the latest version seemed to have solved all of my problems. I really appreciate the quick help and very much appreciate Zenphoto. Thanks!
