Joomla hello world module not working

Question

This is the first time I'm working with Joomla and I try to get started with simple hello world module.

I have created hello world module as described on http://docs.joomla.org/J3.1:Creating_a_simple_module/Developing_a_Basic_Module.

Configured it like this:

But hello world text is not rendered:

I also tried to dump from mod_helloworld.php, but look like it is not interpreted at all. I'm using Joomla! 3.1.5

Any idea what am I doing wrong?

The default Joomla template (Protostar) comes with predefined positions such as position-1, position-2, position-1 etc, however not every single one is defined in the index.php of the template folder and therefore if you assign a module to one of these undefined positions, it won't be displayed.

Assign your module to position-7 which is a pre-defined position on the right hand side of your template. Other modules such the main menu and login also use this position.
