The countdown timer is working great on Firefox and Chrome, but on Safari it is blank—only the background oval appears, no numbers/clock. The error showing in Safari is “`jQuery.Deferred exception: date.replaceAll is not a function. (In ‘date.replaceAll( ‘-‘, ‘/’ )’, ‘date.replaceAll’ is undefined)”

Granted, this is with MacOS Sierra/Safari Version 12.1.2—older but not ancient. Wondering if there is a fix. Thanks,.
