When someone tries to access a file which doesn't exist then your server is trying to find 400.shtml to show / generally its custom error 400 file in cPanel setup .. similarly when there is some internal server error.. generally configuration error related to server  then ERROR 500 pops up..


But what I doubt.. why would someone try to access file public_html/Themes/52400.php
Its not part of SMF setup.. maintain full backup of site and check who is sending those bogus file request..
