On the Dashboard, when creating a visual map Widget, if the map’s background is completely black, it is due to the Apache configuration.
If the Pandora FMS Web console is installed in the default Apache location ( /var/www for Ubuntu) this problem won’t happen, but if we’ve installed the Pandora FMS Web console in another location, for example at /home/user/public_html, then, it will be possible that you encounter issues finding the map’s background image.
