I installed Zenphoto on a test server to get everything up and running and now am trying to copy everything across to a different server which will host the live site. I followed the instructions for the server move but when I run setup I am having difficulties knowing what to put as the MySQL host. I backed up the database and copied across the backup as instructed. Should I have created a new MySQL database on the new host server as well?

Of course you have to create a database (although theoretically Zenphoto can create it itself but virtually no normal host allows that) since you moved on servers which will require most likely be another MySQL server as well.

Thank you for your quick reply. Databases are all new to me at the moment!
