I'm not 100% sure on this, so if someone could double check, that'd be great. I had a client install the OSCommerce software via cPanel today and it went great. He modified it up for about 6 hours today and then tonight decides he wanted 2 more stores.
The 3 stores all ended up using the same database... according to him he didn't make any changes, etc so I'm assuming this is a cpanel bug. I'll check it more in a bit, but I need to get a couple hours sleep so my brain can function normally.
