Broken "vnstat info" tab on pfSense 2.2.6 and vnstat 1.12

[vizi0n]

Hi everyone,

I had issues with the "vnstat info" tab that would not display anything but a gray box when I selected an interface.

Looking into the code of "/usr/local/www/diag_vnstat2.php" I discovered this block of code

if ($_REQUEST['getactivity']) {
        if ($_REQUEST['sorttype']) {
                $sorttype = escapeshellarg($_REQUEST['sorttype']);
        } else {
                $sorttype = gettext("-h");
                $text = shell_exec("/usr/local/bin/vnstat -i {$aaaa} {$sorttype}");
                echo $text;
        }
        exit;
}

By moving the "$text" and the following echo line outside of the if statement, it worked.

Like this:

if ($_REQUEST['getactivity']) {
        if ($_REQUEST['sorttype']) {
                $sorttype = escapeshellarg($_REQUEST['sorttype']);
        } else {
                $sorttype = gettext("-h");
        }
        $text = shell_exec("/usr/local/bin/vnstat -i {$aaaa} {$sorttype}");
        echo $text;
        exit;
}

I hope this can help someone else with that issue
