cPanel problems in WHM - the case of the disappearing website

Hi All,
Right now I only have one cPanel instance running on my VPS. I have more to do but I can't go ahead because that 1 account is not showing up...

1. This account is not listed in 'List Accounts' in WHM
2. I can't access it through its own cPanel
3. I can't access it through its domain address... it tells me there is no website configured to that address.

What are some tests I can run to figure out what's going on...?

Thanks in advance.

 

Thanks for your help Dino.

I checked the file you just mentioned and both the domain and its user were listed there. I also tried some other files in the same area and they had the right domain and the right user...

Any other thoughts?

It is fixed now. I received assistance from my provider and their answer was that the upgrade broke some settings and they just fixed them. (I know it wasn't much of an answer but I guess since it is fixed...)

Thanks.
