title: Linkedin Share Button FORM_INVALID Response
body: <p>I have a problem that LinkedIn share button suddenly stopped working. (It used to work.)  It is created by <a href="http://developer.linkedin.com/plugins/share-plugin-generator" rel="nofollow noreferrer">Button Generator</a>.</p>
  
  <pre><code>&lt;script src="//platform.linkedin.com/in.js" type="text/javascript"&gt;
   lang: en_US
  &lt;/script&gt;
  &lt;script type="IN/Share" data-counter="right"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>And it loads a popup with all content and images without problems and it loads LinkedIn users if I want share it with specific person without problem. </p>
  
  <p>But the problem is that share button on the popup doesn't do anything when it is clicked.</p>
  
  <p>On the Firebug console, it is written...</p>
  
  <pre><code>&lt;WSResponse&gt;
  
  
    &lt;responseInfo&gt;FORM_INVALID&lt;/responseInfo&gt;
    &lt;responseMsg&gt;&lt;/responseMsg&gt;
    &lt;jsonPayLoad&gt;&lt;/jsonPayLoad&gt;
  
        &lt;formErrors&gt;
          { globalError : '',
            inlineErrors: {
  
                'messageSubject-shareForm' : 'The text you provided is too long (the maximum length is 150 characters, your text contains 152 characters).'
            }
          }
        &lt;/formErrors&gt;
  &lt;/WSResponse&gt; 
  </code></pre>
