Hi,

In moving our state wide perfsonar deployment to a central MA and Maddash, 
I'm getting an error when I click into a graph history detail from Maddash.
Error retrieving data from the webservice.  

The initial maddash is here:
http://ps-dashboard.npidev.psu.edu/maddash-webui/index.cgi?dashboard=Penn%20State%20RTM%20Mesh%20Config
