Your .htaccess file must of had a typo in it or something or possibly your host doesn't allow them. It wouldn't just make it not work like that.
Regardless, something is wrong in your php.ini, because this shows that register globals is still turned off. Search for register_globals in the phpinfo page and you'll find this.
Code:
register_globals Off
So your php.ini changes either were incorrect or were done to the wrong file. The phpinfo pages also shows your php.ini is coming from
/usr/local/Zend/etc/php.ini
Is that the file you modified?
Unmodified BOSI 2 code relies on register globals being turned on as it was by default in PHP versions < 4.02 or so.
