With or without modifications, I get the same problem on two different servers:
Whilst the XPages Extlib Demo is working correctly, I can get the homepage application running locally with browser and notes client. Moving the database to the server, it still works in the client (not surprising ....) but when accessing with browser, it is no longer working correctly. Reproduced it on another server: same effect: Demo is working - even in browser - homepage does not. Here is a link to show you, what happens:

As there are no error messages I can find, I have no idea, where to search for this problem
