[rrd-users] Mailgraph 1.14 not displaying Graphs

Hullo users,
I have made a fresh installation of mailgraph 1.14 on rrdtool 1.4.5

I have the mailgraph.cgi to /srv/httpd/cgi-bin and i use
this URL in my browser http://localhost/cgi-bin/mailgraph.cgi, but on
testing the
graphs are not displayed:
Mail statistics for mail-gw3
