      Did a clean install of 23.01 without any issues. One day later I did change the DNS servers in DHCP server for an interface and got that in browser after hitting apply:

      Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/system.inc:422 Stack trace: #0 /etc/inc/system.inc(520): system_hosts_dhcpd_entries() #1 /etc/inc/system.inc(551): system_hosts_entries(Array) #2 /etc/inc/services.inc(2772): system_hosts_generate() #3 /usr/local/www/services_dhcp.php(788): services_unbound_configure() #4 {main} thrown in /etc/inc/system.inc on line 422 PHP ERROR: Type: 1, File: /etc/inc/system.inc, Line: 422, Message: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/system.inc:422 Stack trace: #0 /etc/inc/system.inc(520): system_hosts_dhcpd_entries() #1 /etc/inc/system.inc(551): system_hosts_entries(Array) #2 /etc/inc/services.inc(2772): system_hosts_generate() #3 /usr/local/www/services_dhcp.php(788): services_unbound_configure() #4 {main} thrown

      Going back to dashboard worked. Checking services I saw that unbound was stopped. I can't start it anymore. Trying to reach "Services/DHCP Server" resolves in only showing those lines:

      Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/services_dhcp.php:140 Stack trace: #0 {main} thrown in /usr/local/www/services_dhcp.php on line 140 PHP ERROR: Type: 1, File: /usr/local/www/services_dhcp.php, Line: 140, Message: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/services_dhcp.php:140 Stack trace: #0 {main} thrown

      After that I saw a crash report:

      Last hope was a reboot. Unfortunately this came up while booting:

      Setting timezone...done.

      The firewall booted up but nothing worked. No DHCP, no DNS. I even can't reach WebUI.
      Only way to fixing this was to revert the config from day before. After reboot everything was fine again.

        I can reproduce this by just hitting "save" on the DHCP server tab for an interface.

        After hitting save the webbrowser only show these lines:

        Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/system.inc:422 Stack trace: #0 /etc/inc/system.inc(520): system_hosts_dhcpd_entries() #1 /etc/inc/system.inc(551): system_hosts_entries(Array) #2 /etc/inc/services.inc(2772): system_hosts_generate() #3 /usr/local/www/services_dhcp.php(788): services_unbound_configure() #4 {main} thrown in /etc/inc/system.inc on line 422 PHP ERROR: Type: 1, File: /etc/inc/system.inc, Line: 422, Message: Uncaught TypeError: Cannot access offset of type string on string in /etc/inc/system.inc:422 Stack trace: #0 /etc/inc/system.inc(520): system_hosts_dhcpd_entries() #1 /etc/inc/system.inc(551): system_hosts_entries(Array) #2 /etc/inc/services.inc(2772): system_hosts_generate() #3 /usr/local/www/services_dhcp.php(788): services_unbound_configure() #4 {main} thrown

        Trying to get back to the DHCP server page doesn't work anymore. The WebGUI only shows:

        Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/services_dhcp.php:140 Stack trace: #0 {main} thrown in /usr/local/www/services_dhcp.php on line 140 PHP ERROR: Type: 1, File: /usr/local/www/services_dhcp.php, Line: 140, Message: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/services_dhcp.php:140 Stack trace: #0 {main} thrown

          Doing another clean install and uploading my config resolves in another crash.

          [18-Feb-2023 14:12:14 Europe/Berlin] PHP Fatal error:  Uncaught TypeError: sort(): Argument #1 ($array) must be of type array, null given in /usr/local/www/pfblockerng/pfblockerng.php:1980

#6 {main}

          Also the PHP fatal error stays the same when hitting save on DHCP Server tab.

          Going back to 22.05 seems to be the only solution.

            Do you also have DNS servers defined on that interface? Any other non-default config in the DHCP setup?

              @stephenw10 No, nothing special. I figured out that by reassigning the same IP address via console to any interface that is using the DHCP Server the issue is gone. After that I can edit the interfaces via WebGUI. I think it's related to something in the config backup that is not compatible with PHP8.1.

                Yeah it must be something in (or missing from) the existing config you're hitting. I can't replicate it here.

                  For reference, the pfBlockerNG issue is fixed - currently waiting on the new version to be available. The DHCP GUI issue will also be fixed - track the issue here.
