Drupal 8.x

I am migrating an existing Drupal 7 theme to Drupal 8 using Twigify along with Drush.
While the tpl.php templates being converted into html.twig ones , an error is coming while the page.tpl.php is being converted into its twig equivalent.
The error is: Fatal error: Out of memory (allocated 1947992064) (tried to allocate 36 bytes) in D:\xampp\htdocs\drupal7\sites\all\modules\twigify\includes\luthor.inc on line 407

I also increased the memory limit in php.ini file from 1024M to 2048M but still the same error is coming.

In my custom module (in Drupal 8.3), I am using a form field (in a custom form) to use CKEDITOR with the following code which loads the editor fine.

$form['full_detail_text'] = array(
  '#type' => 'text_format',
  '#format' => 'full_html',
  '#title' => t('Full Detail'),
  '#rows' => 5,
);

The following code saves the posted data in the database.

Hello,
I just tried to install Drupal 8.3.6 the first time.
Alter entering the database I got this error:

Fatal error: Interface 'Drupal\locale\StringStorageInterface' not found in /home/xy210hob/www/home/core/modules/locale/src/StringDatabaseStorage.php on line 10

In the code of "StringDatabaseStorage.php" there is the line:
"use Drupal\Core\Database\Connection;"

On my Server I there is no Directory "Core\Database".

I would be glad if someone can help me

1. Created a testing twig templates in the same folder.
2. Written down the code definition of block in testing block template.
3. Called the extends in the article template for inheriting the testing block template content.
4. And finally the error is coming "A template that extends another one cannot have a body"

Any Suggestion where am i going wrong.

We are trying to configure our Drupal 8 instance for SAML to integrate with CA SiteMinder for Single Sign On.

Can anyone please assist with precise step by step instructions to perform this integration?

Many Thanks !!
