title: TYPO3: TypoScript doesn't work after upgrade 4.2 to 4.5
body: <p>I'm upgrading my typo3 installation from 4.2 to 4.5 and after that my content is no more visible on my page.
  I used a marker </p>
  
  <pre><code>&lt;!--###MAINCONTENT###--&gt;
  </code></pre>
  
  <p>in my template file and had the following typoScript code to fill it with my content:</p>
  
  <pre><code>page = PAGE
  
  page.10 {
    template = FILE
    template.file = fileadmin/Templates/clean.tmpl
    marks.MAINCONTENT &lt; styles.content.get
  }
  </code></pre>
  
  <p>but it don't work now. What can i do?</p>
