I put up a new website that wouldn’t allow me to login and kept giving me an error that said something like undefined method `save_without_session_maintenance’. I double-checked all my controllers and models against another site that was working fine and they all matched up. I didn’t find any bug reports for the version of Authlogic that I was using. The solution was to just deploy the app again. After that, I was able to login successfully. Weird.
