I have installed the latest dev version of commerce kickstart but whenever i want to edit an order i got this message:
Fatal error: Class name must be a valid object or a string in E:\xampp\htdocs\dhl\includes\common.inc on line 7894
I tried the same operation on another site using commerce kickstart dev version but there is no problem in it
I have this module installed in my site: cck phone,commerce stock,field validation,fivestar,userpoints,votingapi
So what could be the reason for this error? and how fix it?
