Drupal 7, language changes back to EN after clicking on any link I have 8 languages on my website. When I visit the website with different language prefix such as mysite.com/da and scroll down to click on any link. The language prefix changes to EN in URL. For example mysite.com/en/about

Can anyone please help me on it? 

Thanks

in configuration, admin/config/regional/language/configure, modify language detection, the order there determinies wich language to use, it depends on how your languages are set, try moving on first place what you think how is confugured your site, set defalut value last. here are my settings on one site, your may be different.
