Hi, Try changing permissions to 777 just to make sure that is not the problem. (chmod -R 777 dir). If it doesn't help, put if back to 555. And also, check if something has changed in the scripts' outputs (mrtg-load, etc)... And last thing: the permissions have to be according to what user and group mrtg is being ran under.
Hope anything of these things help.
