Language not working in multistore

I have opencart multistore enabled on domain .fr & .de with french, german & english languages.

.fr domain set as french language & .de domain set as german language.

Now when i visit the site .fr it doesn't load the french language, instead it loads english language.
(Currently i set french language is default .fr domain)

Likewise .de domain doesn't load german language
(This store also set german langauge for front end)

I want the site, if i view bodybody.fr site then it should be in french site
if i view bodybody.de site then it should be german site.

Please help me to figure out this issue.

You can force the language before the controller is called, based on the domain in the request.
