Settings not working?

please provide a screenshot of what your settings look like

also remember to set correct permissions for the role that needs to use admin language

and I think each user has to set the language they prefer on their user form
user/xxx/edit

Anyway here is very simple tutorial

• download
• put in your sites/all/modules directory
• go to admin/modules and enable
• go to admin/config/regional/language/admin_language
  and select appropriate settings
  my settings are
  - Use administration language on every page except the listed pages.
  - Use admin paths provided by core (checked)
  - Hide administration language on user form (enabled but does not work due to #2046395: Hide widget "Administration language select" from the user form)
  -Hide administration language on node form (disabled)
  - Force use of default language (disabled)
  - Force language neutral aliases (disabled)
  - Use administration language in the administration menu (enabled)
• go to admin/people/permissions and set the Administration language permissions for the role that will use it
• go to user/x/edit and set the appropriate language for each user that will use this functionality

I think these both describe the same problem in different ways...

I think I've found the reason, at least it fixes these problems for me:

In

function _admin_language_user_form_add_language_select(&$form)

(Line 653 of admin_language.module)
a wrong variable was used: "admin_language" which is always empty and so always returns "en" fallback!

$admin_langcode = variable_get('admin_language', 'en');

This has to be corrected to: "admin_language_default".

$admin_langcode = variable_get('admin_language_default', 'en');

Important: This has NO implications on the used admin language, but is just a problem on the Display-Layer.

Please fix in the next release :)

Is this still relevant?

@Liam Morland: Yes I think so. The code is still the same, but now in Line 816 in the latest dev. Of course my assumptions should be checked, but for me this was the reason for the problems.

Can you provide your fix as a patch?

Nope, as written in an other issue I'm now using a different module. Sorry.
