module Yii-user

I’m trying to install module Yii-user, using instructions. But there is an exception:

Alias "user.UserModule" is invalid. Make sure it points to an existing PHP file.

what can be the problem?

Check that your modules directory is accessible by the web server process.

In *nix:

chmod -R go+rx protected/modules
