[balkyd]

Hello,every one!
I just install a weathermap plugin within my cacti.When I finished the work,I find it does't create image and html files in Output Directory. I have change configs and output directory permission chmod -R 777. I can create a new map as a copy of an existing map,for example,my map name is ddd.conf.

When I clicked the Create Copy to submit. The map can create and edit .
