Drupal 8.x

Hi guys. Drupal 8 install, behind a proxy for http/https that works fine for everything but Drupal. In settings.php:

$settings['proxy_server'] = '192.0.0.3';
$settings['proxy_port'] = 8089;
# $settings['proxy_username'] = '';
# $settings['proxy_password'] = '';
$settings['proxy_user_agent'] = '';
$settings['proxy_exceptions'] = array('127.0.0.1', 'localhost');

Whenever I try and update Drupal, I get this:

Hello guys,

I installed Drupal 8 and was trying to do some basic tutorials.
What I have figured out that after clicking Add Content, I just see two links, Article and Basic Page.
If I click article, I just see Title, and then Menu Setting, Revision info, Url.... etc but no body, text format, image.
I am also logged as admin user.
Can anyone tell where the flaw is?

Hello,
I'm a Drupal novice user, and I'm trying to understand how to achieve certain tasks "the Drupal way". :)
I need to specify CSS rules for displaying a particular Field. Is it possible, maybe using a 3rd party module, to specify additional CSS rules specific for displaying a particular Field? Currently I added the said rules in the CSS file of the Theme, but I see many problems doing this:

Drupal running but I'm missing something. Install worked fine and job completed successfully.
There has to be step(s) that is/are evading me.

After going to localhost/drupal , page comes up with my site as heading but when I try which I believe is next step "add content" an error occurs .../drupal/Node/ADD "Page Not Found".

Now, when I look at the path, the sub directory Node is not there. That makes me think that I've missed a step.

Any point type list would be appreciated. Latest Drupal 8.0.2, latest WAMPP, W10.

Thanks in advance.
