Access content with different language

Hi,
I have installed the French translation of Drupal and my users have the French UI. But if a user selects “English” as language in his profil, he has no access to the home page and any content.

How can I give access to all content whatever the selected language is ? I want every one to have access to all my content, even if they are from China, Spain or Russia.

Drupal version:
