At long last I've figured out how to get Apache, PHP and MySql running on my Macbook Pro.
Apache Server and MySql Server are running un MAMP
I'm using VirtualHostX to establish my downloaded site presence.
I've downloaded my WordPress website and exported it's MySql database tables onto the Mackbook.
So it's time to jump into the deep end of the pool.
And I'm getting message:
"Error establishing a database connection"
I need a little help getting the WordPress site to connect on the MacBook.
