Our experience is that the addition of the require once in the two files will fix the problem IF you make sure you are using the correct username in the Start Directory block. Something like /home/freaker/public_html where freaker is your username.
Also, there needs to be a fix to line 418 of the sitemonitor_configure_setup.php in the root of your admin in order to make the update button appear.
It should read
PHP Code:
<INPUT type="image" src="<?php echo DIR_WS_LANGUAGES . $language . 'english/images/buttons/button_update.gif'; ?>"
Make sure there is no slash in front of english.
