Shipping Methods

So in the product do not find anything, I'm just disable the product

Ok, then you have to add some css. Edit the front-end css through hikashop interface in System>Configuration>Display and add these lines:

.hikashop_product_weight_main{
display:none;
}

Thank you very much
I just do not know why I was restored to the English language: (
How do I put Italian?
I went to System -> Language -> Italian
Does not work ... I always fires English.

You should check the Joomla's configuration. In 1.5 go to Extension>Languages and check the default language.
in 2.5 Go to control panel> Language manager and check the default language

Not only with the cart is installed on the English language

I don't understand what you mean. What's you default language in the configuration?
Where do the translations are not available?
