Cannot see Devices in my device list

[manhaak1]

On one of my Cacti serve which is on Linux, when I go to the URL CONSOLE ---> DEVICES , I do not see the list of my devices on right hand pane however I know they are there and on the top where it displays how many rows are available I see it says:
"Showing Rows 1 to 30 of 735 [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21...] "

Anyone seen this issue any pointers what I can check for ??? Help much appreciated.

Thanks...
