I just installed module_manager because I want to use the cross sell mod and am getting a similar error. I tried to use this solution, but I don't even have a file called init_yclass.php. I could not find the shared_classes separately that the readme said to install, but one of the updates said it was now included in the mod (the entire site http://svn.rubikintegration.com seems to be gone). I had assumed the latest download from the zen-cart add-ons section would have the most recent version, but maybe I need to go to that Google link... My version says Alpha 3.3. Apparently, I am still missing files. I'll try the Google link, but any other suggestions would be appreciated. Also, if the add-ons section is not up-to-date, is there anything that can be done about it? Is the support site really gone, or just down temporarily?
