Hi @Giannis Maroulis - Seems that there is a cron job that calls "/usr/bin/php /home/thinklet/public_html/customer/index.php".
Not sure how that happens, can you share here your cron jobs from cpanel?
That looks good, i don't see the connection to customers/index.php file.
Do you have many subscribers in the system?
Does the issue persists, or was a one time event?
I got no customers yet just a test account with 104 subscribers that i upload today morning. Yes i got many yesterday and i got same events today....
