I have a new install of WCS 188.8.131.52 and for some reason the web interface will not display graphs correctly. The alarm summary picture on the main page as well as the Associated cliets vs time graph are not showing up.
Do you have flash player installed for your browser? It is required for both. Also, which browser are you talking about? Firefox is not supported, but works fine in Linux, but not windows (memory leak issues).
