admin crush on plugin update

after upgrading yoast from version 8.0.2 to 9 I receive this error when trying to log into the admin:

[Tue Oct 30 14:30:54.997767 2018] [proxy_fcgi:error] [pid 9384:tid 140576594671360] [client 172.68.62.175:49298] AH01071: Got error ‘PHP message: PHP Fatal error: Uncaught Error: Call to undefined method WPSEO_Utils::is_plugin_network_active() in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wordpress-seo/admin/menu/class-menu.php:27\nStack trace:\n#0 /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wordpress-seo/admin/class-admin.php(32): WPSEO_Menu->register_hooks()\n#1 /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wordpress-seo/admin/class-admin-init.php(31): WPSEO_Admin->__construct()\n#2 /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/wordpress-seo/wp-seo-main.php(389): WPSEO_Admin_Init->__construct()\n#3 /opt/bitnami/apps/wordpress/htdocs/wp-includes/class-wp-hook.php(286): wpseo_admin_init(”)\n#4 /opt/bitnami/apps/wordpress/htdocs/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array)\n#5 /opt/bitnami/apps/wordpress/htdocs/wp-includes/plugin.php(453): WP_Hook->do_action(Array)\n#6 /opt/bitnami/apps/wordpress/htdocs/wp-settings.php(327): do_action(‘plugins_loaded’)\n#7 /opt/bitnami/apps/wordpr…\n’

I have a staging which I’ve installed exactly the same thing but the problem did not occur.

I assume it means the problem is in the db?

thanks for the help.
