I had such good luck with Zencart and OScommerce on the other sites that I have them on. For some reason both of them get error messages on the new site. (Same hosting company, but a different servers)

Thanks for any input, help and directions. !!!!!!!!!!!!!!!!

Other information:
I just opened this account.
Same hosting company as I use for other sites, but all other are shared.
OS works great and so does ZenCart on the shared IP addresses.
