Hi everyone. I had to translate a site into English and I followed all the steps. I activated the English localization, translated the pages and published. I linked the modules between the translated pages and everything seemed to work. But this happens:
I change the language from Italian to English (via flag) and as long as I browse the subpages of a module everything is ok. But when I click on the title of a module that should land me on its main page, the language goes back to Italian. To give an example.
www.xyz.it/qwerty/it-it/hello/mainpage.aspx -- here everything is ok. Than I change the language in eng
www.xyz.it/qwerty/en-gb/hello/mainpage.aspx -- ok i want to go to secondpage.aspx
www.xyz.it/qwerty/en-gb/hello/secondpage.aspx -- ok
In this case i want to navigate from HELLO to ABOUTME module but when I go with the cursor on the module title this link appears
www.xyz.it/qwerty/it-it/ABOUTME/mainpage.aspx -- but i am currently in en-gb/hello/secondpange.aspx. I click, i go to ABOUTME module, i land on the main page of the module but in italian, and than i have to change the language again. 
Another test I did was to change the skin of the site. Currently we i can navigate the site by clicking on the module titles and then see all the pages below once i enters the module and land on the main page. By changing the skin to a different one, I can see all the pages of all the modules without having to enter them. And I noticed that all subpages are ok, so if I'm in English I see the link in English, but if I go on the titles of the modules they stay in Italian. How can I fix?
I have access to db, so if i have to update / edit something i can do but so far I haven't found anything that could suggest a malconfiguration.
Thanks everyone for the help
