Drupal 8.x

I've been struggling with this for a couple days and cannot find a way to do it. 

I have a content type, plant. It contains a paragraph field called locations. 

The location paragraph has two fields. I'm concerned with the location field. 

In my "Plant" view, I can get to the location field - I just add a relationship to the paragraph. But how do I get the parent terms, so I can group by the parent tags. I've tried adding a relationship to the taxonomy and to the term parent. But no luck. 

Hi,

for example, an article website

Part 1

user A submitted one article (pending for admin approval, unpublished)

Admin reviewed and approved (approved, published)

Part 2

user B sees the article, finds mistake, edits the article and submits

Admin either 1) approves the change (new content to overwrite the original content) or 2) disapproves the change (continue to display the original content)

Hi every body,

I have a website which is based on Drupal 6.26, and I want migrate to Drupal 8.1.7.

I have followed this guide: https://www.drupal.org/docs/8/upgrade/upgrade-using-drush

Although, I set up website successfully, and added 3 modules to "modules" folder.

But when I run this command: drush en migrate_upgrade migrate_tools migrate_plus -y

then an error has appeared:

I have the SMTP smtp-8.x-1.0-beta3 module installed and configured to my AWS Workmail account. Everything is configured the way it says in the documentation but I'm still getting the following error when users submit contact forms. 

UNABLE TO SEND EMAIL. CONTACT THE SITE ADMINISTRATOR IF THE PROBLEM PERSISTS.

Module configuration: 

INSTALL OPTIONS: 

Turn this module on or off: on

SMTP SERVER SETTINGS:

SMTP sever: smtp.mail.us-east-1.awsapps.com

Does anyone know how to fix the following PHP Fatal error?. I am trying to upgrade Drupal837 to Drupal853 using drush.

php version: PHP 7.2.2

Error:

PHP Fatal error:  Uncaught Error: Class 'Drush\Config\Environment' not found in /var/www/html/vendor/drush/drush/drush.php:58
