    Answer:

    These PHP errors were being caused by this code in the wp-config.php file:  define( 'ALTERNATE_WP_CRON', true );

    This code is known to be problematic.  If you are running into problems with standard WP Crons then setup a Direct Cron job in your web host control panel.  The correct cron interval is 1 minute.  Any other cron interval time interval is incorrect and will cause problems for Plugins and Themes that run Cron jobs.  After setting up a Direct Cron job add this code in your wp-config.php file: define( 'DISABLE_WP_CRON', true );
