ConligWX, server is on the same device.
freddie, I'm using the same ID and password both places.
Incidentally, I can access the database through a GUI client as well as the MySQL shell in the terminal.
Also, there's a red X in front of the 'Host' box whether I use 'localhost' or the actual IP address of this machine. Do you think that being on a WiFi connection has anything to do with it? I wouldn't think so seeing as I can connect to the database using a SQL client.
