site gone, not found message after I upgrade to 1.1.9 version

[doublethree]

Hi I recently update my abantecart from 1.1.8 version to 1.1.9 version, and I got this message after I upgrade, my site and my admin page as well. So the whole site is gone

Not Found
The requested URL /install/index.php was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

is anyone know wrong with this?
thanks!

Why do you try open index page from install subdirectory?

actually is whenever I open my page, it will direct me to this page.

Do you see any content inside file system/config.php?

[doublethree]

No, it is empty

[abolabo]

No, it is empty

That's answer about redirect.
Abantecart upgrade process never change config.php.
Restore it from backup...if you have it

hrmm, because I download the file from abantecart website, inside got include the file, so I updated it as well.

I just revert back, but my admin page is still not showing

I think is the cache issue, my admin page is back
