You can easily replicate this yourself:
# cd /var/www
# curl http://wordpress.org/latest.tar.gz | tar zx
# mv wordpress mycompanyblog
...then point your webserver to it, and go through the 5min install instructions. That's all I did! 4 times I've done it now, wiping everything - even the server, since this is a completely fresh install on an Amazon EC2 server. Still no luck.
- I'm NOT changing any variables/options/settings by hand; all done through the install script.
- I'm NOT editing any database tables, rows, or data.
- I'm NOT modifying any source code in the PHP files.
I honestly can't believe this; I could understand if I were messing with settings during the install, but I'm not. Download, unzip, point webserver at source, follow instructions... FAIL.
