Multisite warnings in administration

BPS version: 5.5
PHP version: 8.0
WP version: 5.8.2
I have activated the plugin from the main site and not from the network admin.

Oops yeah the cause of the php errors is missing isset() conditions. This will be fixed in the next BPS version release.

To manually fix this now do these steps:
The missing isset() conditions have been added in the code below.
Copy this modified/fixed code into the /bulletproof-security/admin/includes/admin.php file at code lines: 405-416 and overwrite the existing code.

	// Do not display the Maintenance Mode menu for GDMW hosted sites
	$BPS_wpadmin_Options = get_option('bulletproof_security_options_htaccess_res');
	$GDMW_options = get_option('bulletproof_security_options_GDMW');
	if ( isset($BPS_wpadmin_Options['bps_wpadmin_restriction']) && $BPS_wpadmin_Options['bps_wpadmin_restriction'] != 'disabled' || isset($GDMW_options['bps_gdmw_hosting']) && $GDMW_options['bps_gdmw_hosting'] != 'yes' ) {		
	add_submenu_page('bulletproof-security/admin/login/login.php', __('Maintenance Mode', 'bulletproof-security'), __('Maintenance Mode', 'bulletproof-security'), 'manage_options', 'bulletproof-security/admin/maintenance/maintenance.php' );
	}
	
	// 3.2: Setup Wizard Option: Multisite Hide|Display System Info Page for Subsites
	$Mu_Sysinfo_page_options = get_option('bulletproof_security_options_mu_sysinfo');
	if ( isset($Mu_Sysinfo_page_options['bps_sysinfo_hide_display']) && $Mu_Sysinfo_page_options['bps_sysinfo_hide_display'] != 'hide' ) {		
	add_submenu_page('bulletproof-security/admin/login/login.php', __('System Info', 'bulletproof-security'), __('System Info', 'bulletproof-security'), 'manage_options', 'bulletproof-security/admin/system-info/system-info.php' );
	}
