I am developing an intranet with Joomla 2.5 and I have two menu type modules, one for each language (English and Spanish). The type of access for both menu items registered user is of type (pre-installed by default in Joomla).
I have activated the module language change and the auto-login plugin (http://extensions.joomla.org/extensions/access-a-security/site-access/authentication-cloud-based/10508).
When I access the website through the auto-login (I access directly in English) I can navigate successfully through all the menu items. The problem is when language change. Changing the language session is lost and I get the screen with the login form.
Why session is lost? What is the problem?
The problem was not in the core of Joomla. The problem was in a module (which I developed myself) and made a session_destroy(). In addition, this module was assigned to all menu items in Spanish.
I feel have made you waste time. Apologies.
Greetings.
