I can't see the themes of courses in joomla

Hi
I have a menu link for Category courses where are six courses. When I click in some course, then show the course detail and in footer a link to "Themes of the courses". In moodle, I have two themes, but I can't see them clicking in the link. It show me a blank page.
I was searching some option for to display or no the themes of the courses, but I can't find something.
The page with courses is:
www.thefoodspace.com/index.php/es/cursos
My Joomdle 1.0.5 and Joomla, 3.5.1.

Hi.

We would need to see what you have in Moodle course to give you any ideas...
What's the course format? Do you have any restrictions on activities?

Thanks, really was for a different clasification of themes. Excuse me for not to see it. Thanks again.
