Drupal 8.x

Hello

Just a fresh install D8.8.0 with composer in CLI :

composer create-project drupal/recommended-project my_site_name_dir --no-interaction

I want to add a module :

composer require drupal/http2_server_push

Hello.Im new to Drupal.

I created Article node on my website with "+Add content" button.Now i'm trying to change body of my article in my database( in ''body_value'' in the table ''node_body''),but the body isnt changing on my website.

My question is: can i even change content like that?If i can,how do i apply changes from my database to the website?Or i can only Edit my content from my admin menu?Thanks in advance for the answers.

Based on recent discussion topic that started upon coming to know about existence of a very interesting module:: https://www.drupal.org/project/compressed_cache

(For Drupal 8 . . .)

The heading for the baked-in contact form at < /contact > reads "Website Feedback". I'd like to change it. Can this be done with Drupal's user interface, or will I have to modify the Drupal code? (Note that I'm reluctant to tear into to the code to do this--I'd like for this modification to persist through Drupal core upgrades.)

Why go to the trouble?

using softaculous , i updated 8.7 to 8.8. and wish to run update.php

I want to  access  http://website.org/admin/config to put it in maintenance mode  to run update.php

"The website encountered an unexpected error. Please try again later."

I can access everything else in /admin

the drupal log error message is
