[ZendTo] Re: statistics image errors

[bbrendon at gmail.com]

After much toying around I figured out what was wrong. There were two
things I discovered. #2 was the major one and for me it took about an hour
to finally narrow it down!


1. www/graph.php has a bug. Comment out and change. Like below.
//readfile(RRD_DATA_DIR.'notfound.png');
readfile(NSSDROPBOX_BASE_DIR.'www/images/notfound.png');

2. Add this to the very end of preferences.php

// DO NOT PUT EXTRA SPACES OR LINES AFTER THE PHP TAG.
// IT WILL BREAK DYNAMIC/RRD IMAGES
?>
