New language in 1.0

Hi,
I'm trying to install a new language in opencart 1.0.
I have duplicated the folder english in admin and catalog, I have renamed the english.php and I have set a new language in control panel.

All is ok when I load the home page .... I see all the 2 flags ( english and italian ).
But when I click on Italian flag nothin work good.

The front end tell me "Error: Could not load language common/home!" and the admin panel tell me that can't load the language .

I must go to phpmyadmin and I must delete the record with the second language ...... all came back good.

I have also tried to download and install the italian language pack for 0.7 version ..... but don't work good.

There is a guide to install a new language on 1.0 version ?

Thanks for your help.

This is a good point I need to write one. I need to do some testing to see what happens.

It will be great if you can do a translation for me.

Ok Daniel,
but you must tell me what I must translate and what I must do to test it .

Bye.

Sorry for the mistake that i have made an new Topic. I would post reply....
