One thing I learned from reviewing many posts on these "blank pages" issues is that 90+% of the time, the fault lies with the person doing the installing, not in the software. PHP is very sensitive to its environment and to junk in the script (as are all programs.)
My case was no different. The clue was "used GoLive to upload." Well, somewhere along the line, I had opened the index.php file with GoLive, and that (*&^%$#$%^& program added this line to the top of the script:
<?xml version="1.0" encoding="iso-8859-1"?>
This is all it took to blow it up. I discovered this problem by looking at the server error logs, which told me : PHP Parse error: unexpected T_STRING in .../blog/index.php on line 1
For what it's worth to future seekers: look at your own setup before casting aspersions on this fine software.
