I am having exactly the same problem connecting to my database. I’m running Snow Leopard with a custom build of the 64bit MySQL. I’ve a clean install of wordpress 2.8.4.
I’ve configured the database. I can connect via the terminal and via sequel pro. All of the passwords work correctly. With sequel pro I’m connecting at localhost.
I’ve tried setting the MySQL host name to:
localhost
localhost:/tmp/mysql.sock
localhost:3306
127.0.0.1
127.0.0.1:3306
None of which was to any avail. Help anyone?
