All installed, but no stats...?

hi all-

i got piwik installed fine on a VPS and configured several wordpress sites with the code in the footer before the /body tag

problem is, nothing is coming thru to the dashboard… no stats at all.

i haven;t any idea where to start trouble shooting because it all seemed to install just fine…
and there doesn;t seem to be any kind of ‘test’ function to verify that all is working-

anyone have ideas or direction for me?
