Hi, I have a random problem on my site which is that every so often in both the admin and catalog side of oscommerce, I will get a random error saying

A fatal error has occured, register globals turned off

But when I refresh it goes away. I have several oscommerce contributions installed and I cant find out what the problem is. My host have said its not a problem on their side. Register globals is definately turned on.

The server is
apache 2
running ensim 3.7

I would be very gratefull if someone could help me out
