tom_on_wheels My apologies for not replying since. The way your hosting does cron jobs is not favorable due to needing to call a public URL to execute a script. If done incorrectly this could have security concerns.
I see they have an article for how to execute scripts in cron jobs -- I'd recommend following that but making sure you secure the file behind HTTP auth so that nobody else can call upon its execution (I assume you can do that due to the info found on the cron job help page). Again, not ideal.
