I’m also pasting the message from my previous host Web Hosting Canada:
Furthermore, I have checked the forum “Cronjob not working on mautic 3.0.1 - #6 by stefanomarty” that you have provided and noticed that the cron jobs were setup at the root of the server. Please note that your account is hosted on a shared hosting server and because of this, it is not possible to setup cron at the root directory. You have to go with Cloud OR dedicated server to perfrom this root task: Managed Canadian Cloud Servers - Web Hosting Canada || Canadian Dedicated Servers - Web Hosting Canada
