SOLVED jQuery datepicker

[fugo]

WTF
I did exactly the same as you.
I use your head.inc.php.
I put the

Code:

<p>Date: <input type="text" id="datepicker"></p>

directly in the template and get :

Code:

TypeError: $(...).datepicker is not a function

could be because GS is living in a folder not in the root of the site? (Because there is an old site I want to make it pretty with GS).
But nice urls are working, fontawesome worked.

What next?
