I managed to setup a bilingual Drupal 7 page.
All well functioning: All german sites also exist in english.
But the thing: every time someone registers in german, he got an english welcome email. Don’t understand this.
When I looked at the translations at /admin/config/regional/translate/translate, every single email-text exists with its according translation. And at: /admin/config/regional/i18n/variable, in the User emails tab, I checked all fields and saved.
Anyway: if I register, though I got a german welcome message in the browser, the sent email is still english, but should be german.
Did I forget something?
Many thanks for help!
