Graph in Campaign Status not showing

[dhsg]

Hi, not getting the graph in campaign status showing, getting this error,

Warning: fopen(cache/xml/9120e436-9a24-877c-edb3-4518c2086432_campaign_response_by_activity_type_20 07_03_05_2007_03_05.xml) [function.fopen]: failed to open stream: Permission denied in /home/dtoday/public_html/sugar/include/charts/Charts.php on line 76


Have looked in xml directory and that file is not created / not being created - folder has 777 permissions.

Any ideas?

Thanks

I have a similar problem. The issue is in part for me that the permissions automatically get reset to read execute. Does anyone know where these permissions are set? It is a good idea but not everywhere.

Associated questions:

What does sugar run as? Is it a user application? Does it run as root? Clearly something is amiss here because write and execute access and even read access seem like too much for good security. Can someone explain this?

Thanks in advance....
