PHP Users Table Notice on Multisite

We just upgraded a large multisite installation to use version 6.0.11. The upgrade went relatively smoothly, but we’re seeing many instances of this PHP notice in the logs:

WordPress database error Table 'wp_table.wp_304_users' doesn't exist for query SELECT COUNT(*) FROM wp_304_users WHERE user_login = 'admin' /* From example.org/wp-admin/] in [/nas/content/live/website/wp-content/plugins/really-simple-ssl/security/tests.php:139"," */ made by require_once('wp-admin/admin.php'), require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('plugins_loaded'), WP_Hook->do_action, WP_Hook->apply_filters, rsssl_upgrade, rsssl_admin->get_notices_list, rsssl_admin->get_redirect_rules, rsssl_admin->detect_configuration, rsssl_update_option, rsssl_fields, rsssl_conditions_apply, rsssl_conditions_apply, rsssl_has_admin_user, referer: https://example.org/wp-login.php?redirect_to=https%3A%2F%2Fexample.org%2Fwp-admin%2F&reauth=1","Wed Nov 30 2022 13:35:36 GMT-0600 (Central Standard Time)"

It looks like the plugin is trying to access a unique users table for each website, even though a single users table is shared across sites on WordPress multisite.

Are you all able to replicate this notice? In case it’s helpful, we’re on WordPress 6.0.3 on PHP 7.4.

Thanks a ton for taking a look, and for the great plugin.
