Since latest update to 26.7.1, I cannot add Static IPs using the '+' sign on the console of ISC DHCPv4.
I get thrown an error as below:
Deprecated: The backtick (`) operator is deprecated, use shell_exec() instead in /usr/local/www/services_dhcp_edit.php on line 312
I have edited the file removing the (') and adding shell_exec() but still failing (?)
Best use KEA now, it's pretty much feature complete in the GUI.
The ISC plugin is legacy since a while now and EOL.
