title: Index.php deleted by accident
body: <p>My index.php in wordpress was replaced by another one (wrong) and I have no original backup! What should I do? </p>
  
  <p>I tried to get code from oldindex.php but then get <code>Call to undefined function get_header() in /home/taxitaxi/public_html/index.php on line 1</code>. </p>
  
  <p>Functions are invisible! </p>
  
  <p>What should I do?</p>
