I am trying to change the default language for reseller in OA, but it resets back to Dutch. What I would like to achieve is log in under the reseller Brand URL with English language.
In reseller brand interface settings the option
Allow to select language is set to
Use the same language as login screen and login screen is set to use Dutch language.
Set the option
Allow to select language to
user can select language on login screen to make the language selection available at login screen of reseller Brand URL.
Set the Login screen language to
English if you want the English language to be used at the login screen.
Above setting can be changed at Reseller Control Panel > System > Settings > Brands > brand name > Interface settings tab. See additional information in OA 5.5 documentation and in OA 6.0 documentation.
