Hello,
I just noticed that since I created a cron job for EasyBlog a file is generated on the server (SiteGround) every 30 minutes (frequency of the cron job) outside the 
public_html folder, why?

I contacted the SiteGround support and they told me that the problem comes from the component and not from the host ...
Thank you to explain me how to avoid this behavior
