All websites show default website template

Hi
I happened to go to our website this morning and was presented with the default welcome page that is created when you first add a new website.
I then went to a different website and it to showed the same default page, i then visited the other site and they too had the same default page.

So what changed, I did not change any thing.

Running
Debian 10
Ispconfig 3.2.2
Debian is up to date, not outstanding updates ( have not made any updates in the past week)

 

Providing us with better info as guided by @Th0m above is always appreciated.

Generally, if your websites use php, then check if php is down.

 

HI Th0m
Yes it is

 

Hi Th0m
Thank you will follow the guidance and here is the output
