Cron jobs not working

Cron jobs are not running on my website – so my Snapshots are not running and also any other Cron jobs.

I checked with my hosting company and wp-cron is running but it is not running any of the cron jobs.

I have the Crontrol plugin installed and it indicates that the jobs have not run since June. It was at that time I had installed the Heartbeat Control plugin and it screwed up my site.

I did not realize it was not multisite compatible. I did disable and delete the plugin, but I don’t know how to fix this cron issue.
