Drupal 8.x

Hello,

I've just upgraded Drupal on my production site from 8.3.7 to 8.4.0. Before that i had tested it on local environment. All was fine so i've decided to deal with it on my site. Everything went fine i guess, because my site is working, but during installation process i've got one extra PHP fatal error:

For accessing external php library put your external php library under src/ and add a namespace above your external library.

namespace Drupal\YOURMODULENAME\libs;

now in your controller for example ABCController.php use name space as follow

use Drupal\YOURMODULENAME\libs\parseCSV as CsvFilehandler;

use new instance as follow

$xyz = new CsvFilehandler();

In this way you can access external library in your custom module's controller

Hi guys, I'm not sure how I did this...but I did stay out of core (I think)...I've checked all the permissions and it is not a simple matter of my user being anonymous or not.

In my user/registration page I have added some profile fields, and if I access that page with the url (the register link has disappeared for my anonymous browser) I can fill out the information and hit create account.

How can I add some classes to default (or my own created) comments elements so I can target them for adding CSS style.

For example, How can I add some classes or placeholder with using of ThemeName_preprocess_comment to 'subject' and 'name' comments form elements?

How can I target default comments form element?

Hi guys, i really wondering how to pass my variable globaly (page level) so it can be used anywhere.

What i have done:

on my group vars > dev.yml

link: "www.anylink.com"

on my group vars > prod.yml

link: "www.anylink-prod.com"

on my settings.php (j2)

I'm doing a migration from a Drupal 6 site to Drupal 8.4. Unfortunately, when I try to bring over the complete data, the migration fails when converting the user data, which makes a series of other conversions that are dependent on user data fail as well.
