"PublicProfile.Config" Is a folder in the model which contains some configuration. If your menu is blank (can you post a screenshot?) you probably made a mistake in the role configuration.
What is your actual problem?? Did you take a look @ the configuration:
After importing you need to perform the following steps:
Import the DeepLink Module from the AppStore as well
Import the Email Module form the AppStore
In Settings
Set the After Startup microflow to PublicProfile.Startup
In Security
Set Security Level to Production.
Add a Guest user role which maps at least to DeepLink.User, Email.User, PublicProfile.Guest, System.User
Map the User user role to DeepLink.User, Email.User, PublicProfile.User, System.User
Map the Adminstrator user role to DeepLink.Admin, Email.EmailAdministrator, PublicProfile.User
Enable Anonymous users, set its role to Guest, and set Sign-in microflow to PublicProfile.AfterSignIn
In Navigation
set Default Homepage to PublicProfile.AfterLogin
Optionally, add the Email.OpenEmailSetttings microflow and the DeepLink.DeepLinkConfig form to the adminstrators navigation.
In the PublicProfile.Config directory, update all constants according to your situation.
In PublicProfile.LocationForm, add your Google API key. See the documentation of the Google Maps widget for more info.
