500 Internal Server error on ISPConfig w/ Shopping Cart
The site that was on my Host Gator reseller plan is now on my own server. When folks try to check-out (PayPal integrated portal), they receive a 500 internal server error. This only happened when I moved to my server with Fedora 14 x84_64 ISPConfig 3. I contacted the theme designer (WordPress) and this was their quote:
"There is a mod_security rule that is missing that is keeping the cart button from working."
Any help would be great!
