Hi, This is all happen when you update the CWP as I also faced the same issue in the midnight
and one of my customer shouted to me as his website was showing default page. It was an wordpress website
and after digging every where I found an resolution to the issue. Restarted the DNS nothing happen but after restarting
the Apache web server from the CPWP control panel the website came back to live. Why i have restarted the apache is
because I have tried to acces that wordress website backend it was working fine but the main page is showing the issue
so it will because of the web server. I also tried to fix the account permission it won't be work after restart the apache everyhting worked.
