Spree can't update spree_preferneces table

Changes to spree_preferences roll back and there’s no error anywhere but it works in development If the problem is a missing package at the system level then there should be an error The development machine does have a lot of packages installed that aren’t installed on the production machine so I’ve been comparing the two and when I see a package on dev machine not on production I install and see but so far no luck Anyone can help? Please don’t ask me to ask in Spree group it’s not usable and please don’t ask me what not usable means Go there and see for yourself

The spree tag on StackOverflow is active. That combined with http://www.catb.org/esr/faqs/smart-questions.html should help
