Problems with moving my WordPress site to another domain/server

Are you moving WP to new server and domain or new server only? I mean will URL remain the same or will be changed?

There are several things that can go wrong and it is hard to say from details you provided.

Basically:

  • there might be something wrong with your new WP installation, had you just tried clean empty install of WP?
  • there might be something wrong with database move and/or configuration.

See Moving WordPress to a New Server in Codex for general info.
