title: Magento: Change default language
body: <p>I've searched for this for hours again, so here I am!</p>
  
  <p>How do you change the default (English) language to any other language in Magento? Basically, I want all my customer from store B to arrive at the French version of the site first by default, not the English.</p>
  
  <p>Thanks a lot</p>
