Hi,
The CMS is using the wrong language in SS 3.1 - Beta3. I have changed the language for all users (only 3 users) in the user settings, added i18n::set_locale('en_US'); in _config.php & checked the Member table & it has the correct "locale" setting ( set to en_US ) Then did dev/build & flush=all & the CMS still uses the wrong language (I think its africa ? )
Any idea how to fix it or where in the code I can start digging to find a solution (which code in the CMS responsible for setting the interface language ? )
I also found this old ticket : https://github.com/silverstripe/silverstripe-framework/issues/1901
Thanks
