Cacti Poller Not Run Yet

[djchrist74]

I have a new install for Cacti version 1.2.16 on an Ubuntu 20.10 server. I'm new to linux but working on it. I just added a couple devices and I noticed when I go to graphs it says Cacti poller not run yet. I checked a couple things looking at other posts being I have the cron job set to 5 minutes and I verified that matches in Cacti. Below is some info:

I used the below link to set everything up and the only thing different is I had to use PHP 8.0 instead of 7.4 like he had I assume because I used Ubuntu 20.10:

At the end when I setup the cron job I used the below:

*/5 * * * * php /var/www/html/poller.php > /dev/null 2>&1

This is what I see in my Cacti logs and I am not sure this has anything to do with it:

Thanks for any help you can give me.

You need to downgrade your PHP, PHP 8 is a little bit too bleeding edge (I think we fixed most of those in 1.2.17 if I recall, but thats not out yet)
