Graphs greyed out after accidental upgrade to 1.1.19-2.el6

[mathech]

Hi,
After an accidental upgrade YUM from 0.8.8b-7 to 1.1.19-2.el6 all graphs are greyed out. I've rebuild the poller cache and everything seems like it should be working.

Attached is a screenshot of one of the graphs. Any help is appreciated. I looked at several threads of similar issues and unable to. find the issue.

Graph debug output.

Do a graph debug and make sure there is data being populated. It may be that your poller is not running?
