Cacti 1.2.17 is not graphing

[macan]

Dear Macan,
I had been working for it so long now that some of the graphs are working now but the others are not working. I will try to do as you say and send you the log file.

Enable debug for problematic device, in console -> configuration ->settings -> general -> set generic log level to MEDIUM (or more), wait 2-3 poller cycle and show log.
