Hello.
Days ago I added a new measuring points in mesh.json and updated 
pSConfig Templates (mesh.json). The measurement list is updated in the 
archive.
I'm having trouble displaying in  maddash server.
When I updated mesh.json (URL) the archive was updated, the number of 
measurement points in the grid did not update.
Then I restarted maddash server and then no grids are displayed.

mesh.json:
