Subfolders are not working

I reinstalled my OS, made everything from a white sheet.
Now, when i start creating a new site from Dashboard – it’s just loading and loading and nothing happening.

Disable ALL plugins and make sure you have the theme TwentyFourteen in your theme’s folder.

Disabled everything, but has the same thing, loading and loading.
TwentyFourteen is excisting. I even don’t imagine where the problem is.

You’ll want to check your server’s error log, or view the network console in your browser as you load the page to see what it’s trying to call and can’t find.

How can i see networks error? or view network console

Made debugging true.
When creating a site – got the next one error:
postdrop: warning: mail_queue_enter: create file maildrop/630103.28852: Permission denied

I fixed that, but when i created site and want to view it – got Error 404

wp-admin for created site also not working

Server error log.

And the network console in your browser.

https://developer.mozilla.org/en-US/docs/Tools/Browser_Console for example.

Basically you have to do some research to see where it’s erroring, and it’s all on your side :/ When I go, I get this:

Object not found!

The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.

If you think this is a server error, please contact the webmaster.

Error 404

new.khnu.km.ua
Apache

So to me that says server error, and the server can’t read the .htaccess file.

Thank u. The subject resolved. All the problem was with .htaccess file.
