ArpWatch enable database error

[mohammadramadan]

Hello Bro,
Firstly thank you for you great too.
I war enabling the ArpWatch feature, and I received an error regarding the database path.
I have entered the " ArpWatch Database Path" as found after searching it to set it to "/var/lib/arpwatch/arp.dat"
but when saving the settings I recieved the error "[ERROR: FILE NOT FOUND]"

Turn on ArpWatch first It's a 3rd party tool.
