Carousel images within pages content

Hola,
I tried to install template on a site but I can not manager properly, is to complicate.
So I decided to configure on a hot start installation.

Home page are OK but when link to e.g. Summer Holidays
all carrousel images appears between header 1 and articles. Also Main menu do not collapse.
please view capture at

live site is:

can you help me to fix this issues?

On home page you have jquery form some other component, on "Summer Holidays" page you don't have jQuery at all and both menu and carousel needs it.

Thanks Ivan for you quick reply,

but your answer confused me even more. I don't understand why I don't have jQuery.
I suppose this will be included in you default demo installation.
I've only changed pictures and article titles,
I didn't change any article (or site) parameters.

Please notice that by clicking on exactly same articles results are different,
please check by clicking on both:
Home - Espacio SoKraTES
Home- Summer Holidays

one has header1 images but the other no.
I have been reviewing/compare each item parameters and I see no difference

Make sure this lines are present in index.php of template.

No, this lines are not in templates/hot_explorer/index.php (attach your default file)

I've replaced index.php with the one in previous version "hot_explorer31_hotstart" and fixed the issue,
(?)

Can you indicate the diference between old hot_explorer31_hotstart.zip (downloaded last year) and recent downloaded hot_explorer3_hotstart.zip?

I need to be sure before to continue that there will be no problems in the future with updates in a live site.
