IF you can't log in to phpMyAdmin, then your scripts certainly won't work if they're trying to use the same username/password.

Go back into Member Ops MySQL control panel and reset userid password.
Confirm with phpMyAdmin
Then check scripts to ensure they're using same combination of userid/password

I changed all my userid to be different !
It works perfect .
Thank you very much.:D
