I seem to be jinxed with the way phpMyAdmin “celebrates” the publication of one of my books by changing its setup process. It happened twice with Foundation PHP for Dreamweaver 8. I updated the instructions between the first and second printings, but was caught out by a second change. Now it’s happened with The Essential Guide to Dreamweaver CS4 with CSS, Ajax, and PHP. The book was published on 1 December, and on the very same day phpMyAdmin 3.1.0 was released, changing the setup procedure yet again.
I’ll create a full tutorial on the revised procedure when I get time, but you can find a summary of the main differences on the updates page for The Essential Guide to Dreamweaver CS4.
