rrdtool says: graph access denied

[awen]

When I try to see the graph appears the message

"rrdtool says: graph access denied"

and I cannot see any graph

I have a debian 3.1,
mysql-server-5.0 (version 5.0.18-3.dotdeb.1 )
cacti 0.8.6c-7sarge2

[awen]

When I executed graph.ph manually some errors come into view.
