I was moving a prod wordpress blog to a dev environment for development work. I have been following these instructions. The domain name is going to change. I have edited the wp-config.php file with the new names and database credentials. However, I keep getting the same error over and over again: Error establishing database connection I have been troubleshooting this for 2 days now. I now suspect that the database needs to be changed in some way. I faintly remember that the last time I moved a wordpress blog to a different domain… I had to run some kind of database cleanup script. Hmmmm…where was that information 🙁 got it…
