["Petrit Podrimja" <podrimja () ipko net>]

My output module in snort is a database. I can see all the logs to that
database but there is an option for displaying all logs with pie charts
and all those different charts. 
I get this error when I click to that link:
 
Warning: is_file(): Stat failed for /root/jpgraph-1.12.2/src/jpgraph.php
(errno=13 - Permission denied) in
/home/httpd/htdocs/acid/acid_graph_common.php on line 37
Error loading the Graphing library: from
"/root/jpgraph-1.12.2/src/jpgraph.php" 
Check the Graphing abstraction library variable $ChartLib_path in
acid_conf.php
So I'm asking if anybody can help me.
Thanks
