Hi mydakota,
I had/have the same issue on a Crazy Domains on a shared server.
I feel it's definitely a CD issue, although they insist is a ZC issue and to talk to the developer about fixing the issue. It happened to my site a little while back, after they updated their servers.
i haven't been able to find a fix for the issue here in the forums or online and my attributes for products currently doesn't work. I have implemented a Neanderthal technology solution, basically advising customers to enter their attribute options in the comments section of the special instructions form of the checkout forms - most do, but now and again a customer forgets or overlooks entering the details and a simple phone call is in order to determine the customer attribute options.
So the bottom line, until I get time to rebuild the site from scratch my Neanderthal solution will have to do.
Good luck sorting out your issue. :)
kind Regards
les :)
