Monitoring Service plugin does not display graphics

Hello Everybody!

I have a problem (with English, at first ):

I installed openfire 3.10.2 (in Elastix), then set the plugin Monitoring Service, but faced with the fact that incorrectly displayed graphics, or rather do not appear at all. Details in the image.

P.S. I tried in different browsers.

  1. install Elastix 2.5 3) install new version openfire 3) install plugin = now, i have f problem

Will try and reproduce the issue on my test machine and if so come back with some idea of what the issue might be.
