title: Buddypress: Language not changing
body: <p>I'm getting crazy because everything seems to be fine, but impossible to get a solution.</p>
  
  <p>I want to translate my buddypress to Spanish.</p>
  
  <p>Seems like I have everything ok:</p>
  
  <p>My language files:</p>
  
  <p><img src="https://i.stack.imgur.com/Lbaeb.png" alt="languiage files"></p>
  
  <p>My wp-config</p>
  
  <p>define('WPLANG', 'es_ES');</p>
  
  <p>My config on dashboard: <strong>Setted to Spanish</strong></p>
  
  <p>My wordpress version : 4.1.</p>
  
  <p>My wordpress is translated ok once I set the language on the dashboard, anyway the <strong>buddypress language does not change</strong>.</p>
  
  <p>Any Idea about what could be wrong here??</p>
