body: <p>I have a webpage with this header.</p>
  
  <p>It's a non interactive page with just twitter bootstrap js.</p>
  
  <pre><code>&lt;head&gt;

  <p>I saw some posts on stackoverflow but couldn't understand how to fix this.</p>
  
  <blockquote>

  <p>I tried to change the <code>&lt;meta&gt;</code> to</p>
  
  <pre><code>&lt;meta content="text/html; charset=utf-8 ;script-src 'self' http://onlineerp.solution.quebec 'unsafe-inline' 'unsafe-eval';" http-equiv="content-type"&gt;
  </code></pre>

  <p>any idea?</p>
