Dan,
I was able to fix the errors originally by chmodding all files to 777. Then I went through an automatic install, nothing manual. I had it do all the mods, and it said it completed successfully. When I went to confirm this, all I saw that it did was make the changes in index.html of forums dir. It also added the 1 forum and both threads and both posts. Other than that, it didn't finish the install. When you get the time, much help would be appreciated as this is an excellent hack I'd like to see operational.
