Hi All!

After the upgrade package arpwatch to version 2.1.a15_6, when viewing the log, message appears: -
"Fatal error: Call to undefined function gentitle() in /usr/local/www/head.inc on line 26"

pfSense ver. 2.0.1-RELEASE (i386)

Here is the contents of this line: -
$pagetitle = gentitle( $pgtitle );

Friends!
Please tell me what is wrong.
