Thanks for your help Jason
The error when trying to open phpMyAdim is:
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.
In Navicat the is a"tool" called Console
Navicat suggested I ran GRANT ALL PRIVILEGES ON *.* TO 'YourUserName'@'YourIP' IDENTIFIED BY "YourPassword"; in a command line I have carried this out but it produces an error.
I am attaching a picture of the command line perhaps you can see where I am going wrong.
