apparently, the app is not fully tested. you should have qa env that
is similar to prodxn. like dev->qa->prod

we need to get a dump of the error so we can help. see
http://guides.rubyonrails.org/debugging_rails_applications.html

<speculation> Klass + _load error usually occurs on Marshaled
objects... marshall version is independent of ruby version, so be
careful. ie an obj marshaled dump in v1 may not be properly marshaled
load in v2...
</speculation>

kind regards -botp
