As of that change, the only Catalyst::Plugin module you should be using for authentication is Catalyst::Plugin::Authentication. It will use other modules which live in the Catalyst::Authentication namespace rather than the Catalyst::Plugin::Authentication namespace, where older modules used to live. In theory the older ones should generally still work thanks to backwards-compatibility shims, but you might see problems with them over time.</div><div><br></div><div>What version of Catalyst::Plugin::Authentication are you using?

Class::C3 is what Catalyst and DBIx::Class use in order to handle object inheritance.</div><div><br></div><div>Could you share with us the code from your app's startup file which loads the Catalyst plugins, and also the relevant lines from your config file?
