OK, all I had to do was hit the red letters "clicking here" and it solved the problem. Please bear with me, I'm quick to panic when things don't go smoothly the first time!
I seem to have hit a roadblock here:
Recommended PHP parameters
PHP register_globals option is enabled X
PHP magic quotes option is enabled X
PDO MySQL extension is not loaded X
The third grey face will not turn into a green smiley face until I discover how these three issues can be addressed. And I'm not sure where to look! Apparently a php.ini file is involved but I can't find such a file.
