ISC DHCPv4 Static Button throws PHP error

[borito]

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.
