 * I built a WP site on one server and am now trying to move it over to another 
   server. I created a backup of the MySQL database and all the files. I uploaded
   all the files via FTP no problem. I then created the database on the new server,
   imported the backup (successfully), and edited my config file to match. But all
   I get is a 500 server error. So I created another (empty)database, edited the
   config to match, and it works fine. But when I try to switch back to the first
   database it fails again.
 * What am I doing wrong? What is it about full database that might not be working?
   Are there are setting, version numbers, or anything like that that might need
   editing?

 * Thanks. I deleted everything and started over going through those steps. I’ve
   got WP installed, the correct theme active, all the plugins are there, etc. So
   that’s good.
 * But it still won’t connect to the database with all the existing posts, etc. 
   in it. Connects fine to the new db I created for installation but when I either
   try changing to the full db or copying tables across, it gives me a 500.
 * So, what does that mean? Could the db that won’t connect be a different and incompatible
   version, if such a thing exists? I’ve moved WordPress sites between servers before
   and never had this trouble and I’m at a bit of a loss.
