There was a problem applying your settings.
Debugging information:
PHP error (2): implode(): Invalid arguments passed in /var/www/html/admin/scripts/pi-hole/php/savesettings.php:741
Details about my system:
Raspberry Pi3B+
What I have changed since installing Pi-hole:
Nothing changed - just an in place upgrade
Just to be sure, I rebooted RPi, proceed to flush network. Saw two messages
one with error while on top it shows The network table has been flushed for a quick couple of seconds. It seems to have completed network flush despite that error
