It sounds like maybe you didn't add the ebin directory to your class
path, or you didn't recompile the app from Yaws once you restarted
yaws. There are 3 options:
- Start yaws with the -pa argument pointing at your ebin path.
- Start yaws in interactive mode and then call code:add_path() with
your ebin path.
- Start yaws in interactive mode and recompile your app with erlyweb:compile().
