Hello to everybody!
I'm new to ZenPhoto and I had installed latest version on my webspace with a subdomain (mf.melian.de) to check out all features, espacially upload direct from Lightroom with plugin from Joe Philbert.
After some time, plugin is ready for use I want to change my domain to its original domain www.meian-fotografie.de.
Now I have the problem, that I can't login if I start with my domain. I can login on my subdomain, but I want to change it.
Can some help me?

You have to re-do the installation if you change domains.

Thanks for your answer, thats what I want to avoid.

To be specific, you only need to re-run the setup script if you are on the same server.
