So the problem appears to be multiple instances of Fatal error -- undefined constant causing the page to abort.
The strings to change are (do global replacement) in wxnoaarecords-include.php :
date(n) to date('n')
date(Y) to date('Y')
date(j) to date('j')
date(m) to date('m')
I found the fatal errors on lines 419,441,610,611,613.
Leave the settings at the top of the script to ini_set('display_errors', 0);
error_reporting(E_ALL ^ E_NOTICE ^ E_WARNING ^ E_DEPRECATED);
otherwise your error_log will be FLOODED with Warning and Notice errata .. I'd not fixed any of those.
