Unable to open /cf/conf/config.xml for writing in write_config() when set easyrule from ssh

[codauit]

I am using user "ssh" and assinged admins group to ssh pfsense from another server.
When i set easyrule such as "easyrule block wan 192.168.2.3", i met a bug from webGUI: "Unable to open /cf/conf/config.xml for writing in write_config()" and rule not was added on firewall rule.
Please let me know if you find out solution
Thank you

You have to use the root/admin user to do that, or install the sudo package and run the command using sudo to allow your low-privilege account to take an action like that.
