Hi, Have you installed the php-graphviz plugin? The object map functions relies on it. Could you click on ‘object map’ And send me everything that may relate to racktables from /var/log/*error.log? Cheers, Max.

When i try the button named Object map, nothing happens. Internet Explorer says that the page cannot be displayed, and chrome just shows me a blank page. Same thing happens if i try to click on the port name all the way to the left. Is there a problem with my installation? Mvh/Best regards Tormod Hope IT Consulting Engineer
