I have 4 languages and 2 domains: site.com site.eu I set up languages in these domains like:
site.com - english (default)
br.site.com - brazilian
site.eu - german
fr.site.eu - french
When I try to type Site Name for french and brazilian it does not save the line. but it save Slogan. So Drupal use default site name of default language for both Brazilian And French sites: br.site.com and fr.site.eu
this instruction did not help me http://reyero.net/drupal/internationalization_domain_access_multilingual_variables_for_each_domain
There are Realms information that I've found. But how to configure correct I do not know.
