WordPress site went missing and CSS effect doesn't work

I am trying to access an internal Wordpress blog that I've deployed like the following:

Because when I type the servername, it only displayed the plain HTML without the CSS effect开发者_StackOverflows and then when I try to go to the admin page it failed as well.

However when I go to servername/phpMyAdmin all is working well and the Apache server is listening on port 80.

The fact that you're seeing the blog content means that WordPress is installed and is working. If you're not seeing the CSS, it's likely a permissions problem of some kind with the files in your installation directory. If you're running suexec or some other SU wrapper, for example, make sure all the files have write and execute permissions removed (read only) at the group and other levels.
