Nagvis problem


I have fedora 14 and installed nagios. Now i also installed the latest version of nagvis and the installation went fine with the guide of the nagvis website. But when i go to localhost/nagvis i get an error: “The path “…/…/…/var” is not writeable”. I checked the paths in de config file of apache and that is all correct. Does anyone know what the problem could be?

have you installed from rpm or from source?
