Moving site generates ERROR

[Gary]

<_< The site works fine on my test location but when I move OS to its proper location it generates the following error?

Missing argument 1 for order() in /usr/local/etc/httpd/vhosts/mysite/store/includes/classes/order.php on line 16 as well I receive an XML parsing error in Canada Post Shipping MOD.

 

I am just moving the files from the htdocs directory to the vhost directory. I have changed the paths in the OS config files to address the move. OS seems to work well except when I go to the checkout.

I have tried the website with both my SSL socket enabled and disabled.

 

Any help would greatly be appreciated.
