Installing Drupal

I am experiencing serious trouble with my site. After a failed update and failed recovery attempts, I have been seeing various core errors (according to which attempt, they were different, but all were related somehow to core, if I interpret the error message correctly).

The current error is: ""Fatal error: Interface 'Drupal\Component\Plugin\Discovery\DiscoveryInterface' not found in /web/htdocs/www.mysite.org/home/core/lib/Drupal/Component/Plugin/PluginManagerInterface.php on line 28"

The page about installing Drupal 8 suggests this command:

composer create-project drupal-composer/drupal-project:8.x-dev mydir --no-interaction

This uses something called drupal-composer/drupal-project to set up a new Drupal 8 website with all required libraries – and some libraries that are not required on a production site.

So I have a new D8 site that I have built with Composer using the drupal-composer project. I also used Composer to require all of the contrib modules that I needed for my site along with one patch that was needed for one of my contrib modules. I now have my D8 site all working how I want it with my custom content types, menus, languages etc. all using Composer.

Hello,

My website is in marathi language,when i search article title in marathi it works properly, but when i search that name in english its not working for me. i insert that name in marathi as well as in english language while create an article. but english search is not working.

Hope you will help me.

Thank You

Hi guys. After many years of other versions I finally decided it was time to have a go on D8. I made a clean install with composer:

composer create-project drupal-composer/drupal-project:8.x-dev drupal --prefer-dist --stability dev --no-interaction                                        

When I browse to the site I get this:

Hi All

Trying to install drupal-8.7.7 on a centos7.x server with external PostgreSQL . 

Using the browser UI to install drupal and on the "Database configuration" page.

With providing all credentials and database info on the Drupal UI, the page is throwing following error

SQLSTATE[08006] [7] could not connect to server: Permission denied Is the server running on host 'x.x.x.x' and accepting TCP/IP connections on port 5432?.
