Hoping one of you guys ran into this problem before. I’ve installed Mangento successfully and started adding products thru ADMIN just fine. During this process I’ve had to change the root mySQL password for security reasons. Once I’ve done that my store no longer worked and showed this error instead. Makes sense since I’ve changed the mySQL pass.

Reading the forum I read that you can go to you app/etc/local.xml and adjust your db password.
So this is the line of code that I changed to my new password.
Nothing changed.. Still same error.
