In first page of cacti-graph, graphs are missing

[malghul]

Hello,

I have installed cacti 0.8.6g on linux.. I monitor the linus eth0 interface and some mounted disks without any problem.. The issue here is when I get to the first graphing page of the cacti tool, it seems that some pics or graphs are missing, when I click on the area that holds these missing pics or graphs, I get the graph with data..

Do you what the problem might be?
