Answers.Body: <p>I could solve the issue by myself.
  Before deleting a site within the site settings (settings -&gt; sites)
  i had to disable/deactive a site within the settings of a section, wait until all entries are automatically saved again and then delete a site.
  Not sure if this is the expected behavoir, i think in the past i just deleted a site right away in the settings.</p>
