title: TYPO3 Extension FAL record save failure in BE
body: <p>When I try to save a record of my extension I get an "Attempt to insert record on page '[root-level]' (0) where this table, sys_file_reference, is not allowed" error.</p>
  
  <p>I can easily save the record if it doesn't contain any file relations (like images).</p>
  
  <p>It worked until I updated my extension yesterday via extension_builder and the TYPO3 Core from 6.2.12 to 6.2.13.
  Since then I get the error above.</p>
  
  <p>I included <code>'rootLevel' =&gt; -1</code> to ext_tables.php, as described here.</p>
  
  <p>Maybe it's somehow related to this <a href="https://forge.typo3.org/issues/57515" rel="nofollow">bug</a>.</p>
  
  <p>Has anyone experienced this kind of behavior?</p>
  
  <p>Thanks for the replies.</p>
