 * Hello. I just installed this highly recommended plug-in. When I go to edit the
   options, I get the following error message:
 * Hebrew date format
    Fatal error: Call to undefined function gregoriantojd() in/
   data/demo/wp-content/plugins/wordpress-hebrew-date/heb_date.php on line 17
 * This is a brand new WordPress installation. How may I correct this error?
 * Thank you for your time.
