How can a user select a different language to the site default language? My Drupal 6 site should always display in French for all users except me. I need to administer the site in English.

Using the Locale module I have both languages installed and default set to French. In the language negotiation settings ('Configure'), I have selected 'none'. The help text says that "users may (optionally) select a preferred language on the My Account page".

Even though I have selected English in my account settings (under "Language settings"), everything remains in French when I login?
Have you tried using the Administration Language module? 


  This module lets the administrator see all administration pages in her preferred language.
  
  You can use this to display the frontend of the site in one language and still keep most of the backend in English (or another language of your choice).
