Can't show data in graphs

[webproger]

Hi @ All

I've a problem with my cacti installed on RedHatEnterpriseLinux5.

I take a backup of my Cacti-DB and of the RRA-Files, then I installed the Workstation new (it's a virtual machine). I installed cacti(same version 0.7.8b) again and import the backup of the old cacti-db and the rra-files. but now in the graphs-image is no data and no graph. can you help me?

As information: The Spine-Poller I have is running without problems:

thanks!
