title: Wordpress Open Social Error:"Strict Standards: Only variables should be passed by reference"
body: <p>I am using the <strong>Open Social Plugin</strong> in <strong>Wordpress</strong>. I also installed the Debug Plugin to see what is going on. I get a <strong>PHP Error</strong> saying:</p>
  
  <blockquote>
    <p>Strict Standards: Only variables should be passed by reference in /wp-content/plugins/open-social/open-social.php on line 111.</p>
  </blockquote>
  
  <p><strong>Line 111 in open-social.php:</strong></p>
  
  <pre><code>'google'=&gt;"http://translate.google.com.hk/translate?hl=".(isset($_SESSION['WPLANG_LOCALE'])?$_SESSION['WPLANG_LOCALE']:'en_US')."&amp;sl=zh-CN&amp;tl=".(isset($_SESSION['WPLANG_LOCALE'])?reset(str_split($_SESSION['WPLANG_LOCALE'],2)):'en')."&amp;u=%URL%"
  </code></pre>
  
  <p>Does anyone know what is wrong with this line? I am stuck here.</p>
