Well, the new server is PHP5.2.0 and MySQL 5.0.27... should that still work?

I can downgrade PHP easy enough, but downgrading MySQL would be a whole new adventure.

As for the paths... I'm just trying to do a clean setup right now to make sure table names are created correctly (another part of the adventure is that under Windows on my original machine, all existing tables were created in all lowercase... that is not playing well with the scripts on the new Linux box with Linux being case-sensitive with table names (Windows isn't)). With a clean /public_html/ with just the 6.5.5 files in there, I get a white screen from install.php.

I shouldn't have to specify paths in config.inc and ubbt.inc before I do the install should I? I don't recall doing that in the past, but then again it's been quite a while since I've had to do it.

Jesus was an architect previous to his career as a prophet
All of a sudden, I found myself in love with the world
So there was only one thing that I could do
Was ding a ding dang my dang a long ling long
