Issue with view store after install

[DetroitOnline]

I just installed Zencart and I'm getting an error when I try to view the store:

Fatal error: Call to a member function on a non-object in /srv/www/htdocs/airtool/e-airtool.com/htdocs/zencart/includes/autoload_func.php on line 89

The Admin section works fine, I'm running Apache 2.0.58/PHP 4.4.2. Now I just installed both Apache and PHP, before the server was running Apache 2.049/PHP 4.3.2 and it was compiled without session support (thanks to SuSE CD install). I was testing the new version of Apache/PHP on port 8000 and I got the above error when I tried to get into either the store or the admin section. I know have Apache 2.0.58/PHP 4.4.2 running on port 80 and now I can get into the admin section of the store and do things there but I keep getting this error when I try to view the actual store or even the demo.

Any thoughts on this? Something I missed in the PHP configuration?

Well I found the issue. It seems that session.autostart was turned in my php.ini, after turning it off and restarting apache the problems went away.
