Actually using 3.4.3, but it was not a choice.
I have two WP databases. One which is merely a shell which only houses my credentials as the WP owner. My config file has always pointed at it, even though all of my posts+ (including all subsequent plugins) are housed in a second db. Everything worked until I changed the passwords on all the db.
I changed the config to the new password. Result: connection error.
Should I or can I bypass the shell and point directly to the db where the bulk is considering the message from WP says it cannot connect to the bulk db?
