I activated "Redirect returning visitors to last viewed language" with path prefix localization. some pages are in French and are not yet translated in English. when i check english button, the french page is reload but the following messages appear :

Notice : Undefined variable: _SESSION dans include_once() (ligne 18 dans /homez.331/greencod/www/sites/all/modules/languageinterface/languageinterface.module).

Notice : Undefined index: cli dans include_once() (ligne 27 dans /homez.331/greencod/www/sites/all/modules/languageinterface/languageinterface.module).

When "Redirect returning visitors to last viewed language" is desactivated, a 404 page appears and there is no error messages.
