Did you create a department for EN and a Department for FR?
Did you also create a ticket filter to send requests to the EN address to the EN department, and FR requests to the FR department?
The web page should detect the language requested by the web browser, and if that fails when the person logs in it will detect the language set in their profile.
The system can have assigned Templates for each department. So you would set the template (EN or FR) to the department for each.
