Solution to PHP Fatal Error with 1.0.2

I have update to 1.0.2 and my site has crashed.

I fix this changing two lines in includes/class-wc-legacy-rest-api-plugin.php

Line 102.
From:
private function hpos_is_enabled(): bool {
To:
private static function hpos_is_enabled(): bool {

Line 111.
From:
self::remove_notice( ‘legacy_rest_api_is_incompatible_with_hpos’ );
To:
WC_Admin_Notices::remove_notice( ‘legacy_rest_api_is_incompatible_with_hpos’ );

These changes have fixed the error on my site
