PHP Fatal error … undefined function current_datetime()

Too bad, the plugin works fine here also in older classic 4.9.x WordPress installations before the current_datetime change in plugin.

As it seems it would be enough to add these few lines to the plugin to maintain existing pre 5.3.0 WordPress compatibility:

/* Shims for WordPress 5.3.0+ functions in wp-includes/functions.php */
if ( !function_exists( 'current_datetime' ) ) {
	function current_datetime() {
		return new DateTimeImmutable( 'now', wp_timezone() );
	}
}
if ( !function_exists( 'wp_timezone' ) ) {
	function wp_timezone() {
		return new DateTimeZone( wp_timezone_string() );
	}
}
if ( !function_exists( 'wp_timezone_string' ) ) {
	function wp_timezone_string() {
		$timezone_string = get_option( 'timezone_string' );
		if ( $timezone_string ) {
			return $timezone_string;
		}
		$offset  = (float) get_option( 'gmt_offset' );
		$hours   = (int) $offset;
		$minutes = ( $offset - $hours );
		$sign      = ( $offset < 0 ) ? '-' : '+';
		$abs_hour  = abs( $hours );
		$abs_mins  = abs( $minutes * 60 );
		$tz_offset = sprintf( '%s%02d:%02d', $sign, $abs_hour, $abs_mins );
		return $tz_offset;
	}
}
