Weird instance

Hi, I had a problem today in the morning which I am still trying to figure it out, so it does not happen again.

Somehow a lot of files from public_html got deleted, except one folder. I did not delete anything. Basically the whole website went missing.

How can I check logs on what happened to these files?

All I did today was yum update and then upgrade cyberpanel to the newest version, I hope this was not the problem.

Thank you

I experienced a similar issue twice, no one replied anything. In my case whole public_html folder was deleted.
