Cacti Will not display graphs when poller is set to 5 minute

This is a bizarre issue and i know i am probably just missing something extremely simple but here is the issue in a nutshell.

When i poll devices on a one minute poll things are fine and there are no issues what so ever. But when i change the polling interval to 5 minutes on both the console and cron job things do not update and the graphs are blank even though cacti is saying that it is updating these graphs.

When you try and add a new device and graph it under 5 minute polling it comes up nan.

I am currently running 0.8.7b and am using the spine poller. When i change to the cmd.php poller the issue still exists.

Any help would be greatly appreciated.

Any time you change the cron or poller interval you must repopulate your poller cache.

When i change the poller from 1min to 5min , then go to rebuild poller cache, i get lots of this: Warning: Division by zero in /www/htdocs/cacti/lib/api_poller.php on line 119

Putting it back to 1min works.

So aside of this not working, when its set to 5min and i click the green circle to re-index certain things, I get the api_poller.php error as well.

I'm starting to think its template related cause i have all kinds that were imported, but how can i figure out which one?
