Fatal Error: Redefine Class ERROR after transfered to a Window Server

We had developed our store on a PHP server and found out recently that the client needs it on a windows server to work with their other applications.

After making the transfer and setting up the store to run properly I am getting a weird error when attempting to continue to the Check out page from the shopping cart:

Fatal error: Cannot redeclare class order in C:\Inetpub\vhosts\oralabs.com\httpdocs\includes\classes\order.php on line 1002

I checked (from a older post) and there were no duplicate instances of cache.php... Anybody know what this error is and how i can resolve it?

line 1002 is only a closed bracket " } "

Dchrastil:

Fatal error: Cannot redeclare class order

you probably have more than one copy of the order.php class file ... perhaps in other folders
