On Joomla 1.5 the redirect function is using the mosRedirect function which is no longer supported.
To enable it you should change line 503 of chronocontact.php
502 if ( !empty($rows[0]->redirecturl) ) {
// change this:
503 // mosRedirect($rows[0]->redirecturl);
// to:
503 $mainframe->redirect($rows[0]->redirecturl);
504 }
