Disabling auto-translation from English to another language? I've installed Drupal 8 and setted the site to be in Hebrew. It was changed to Hebrew, but from some reason, all the management system area\navigation\menues themselves were also translated to Hebrew. Such a thing never happened to me In Drupal 7. 

In Drupal 7 when I was installing sites and setting the language to Hebrew, I would only have everything moving to the right (Hebrew is an RTL language) and the usage in the language became available, but I never, ever, had all the site translated automatically. 

Is there a way to allow Hebrew without translating every part of the site to Hebrew?
You can configure the administration language seperate to the content language by setting:

/admin/config/regional/language/detection:
Account administration pages: enabled


If you want to force this, set this setting at the top of the list.

Then there is in the user configuration of admin's the option to set a different language for the site and the administration pages language.

For other roles, just set the permission "Use the administration pages and help" to allow this setting to appear on the user page.
