Drupal 8.x

Hello,

I've asked in stackoverflow too, but got no answer, so i hope somehow here can help me a bit.
I am new to Drupal, espacially to Drupal 8.

I have created a View and placed this view in a block called 'views_block__view_submenu_ihk_kurse_block_1' in the header region of my block layout.

Now i try in a preprocess-function to get the content of this block.
I get some variables with:

Hello! I have a problem while making a backup by the command:
$ drush ard --verbose

It returns an error related to database dump:
"..
Calling system(pg_dump drupal --host=localhost --port=5432 --username=drupaluser --no-align --field-separator=" " --pset tuples_only=on --clean > /tmp/drush_tmp_1486406348_5898c2cce9cec/drupal.sql);
/usr/lib/postgresql/9.4/bin/pg_dump: unrecognized option '--no-align'
Try "" for more information.
Database dump failed [error]
.."

Hi,

I'm a beginner with drupal/wamp and i don't speak english. Sorry.

Wamp is ok. Drupal too. But if i install a module, (admin toolbar, webform,....) A fatal error message appear:

Fatal error: Cannot instantiate interface Drupal\Core\Cache\CacheBackendInterface in C:\wamp64\www\drupal\core\lib\Drupal\Component\DependencyInjection\Container.php on line 268

Hello Drupal community !

I've just installed D8 avec somes years using D7.

First step : change the site name.
I've changed site name in /admin/config/system/site-information

But a default name ( => here: "Drupal" ) is always displayed.

"Drupal" is displayed when I call "@site" or "@s". Any tips ? Any help ?
Thank you,

Does anyone know how to display a custom form (i.e. one I've created) on a web page (Basic Page), in Drupal 8?

I Googled this. Some people say to create a block with a form in it, however I want a custom form to display within a Basic Page. Other people suggest putting code inside the template, however this doesn't feel right, as I only want the custom form to display on a single Basic Page, not all pages.

Other suggestions mainly talked about how to do this in Drupal 7, and other people said things had changed in Drupal 8.

Lets, say, not so very hypothetically, that you have the following situation:
