Answers.Text: Yes, it is enabled. All changes are stored in the database tables named "log_[table_name]" (I can list them via phpMyAdmin).

Body: <p>I try to show (first for the admin user) all changes for a contact. That works on Contact's Activity Log page. I can see the date and time of modifying my custom fields, but the old and the new values are not shown. In the databases log table for the custom field are the changes logged. </p>
  
  <p>How can I fix this? </p>
