I tried to update a rails site going from 2.3.5 to 2.3.15, which failed. I had a backup of the site which I restored, but the site still will not start. It errors with:

undefined method `name' for "actionmailer":String

The older versions of 2.3.x get very cranky indeed with modern versions of Rubygems. Try rolling back to something of a more appropriate vintage (I’ve got an old 2.3 app that uses rubygems-update 1.4.2 successfully).
