Drupal 8.x

Hello, I am struggling to migrate a Drupal 7 website to Drupal 8, without drush. I have followed the official guide: https://www.drupal.org/upgrade/migrate
The "update" process works properly until it reaches 100%, after suddenly the page becomes white with this error: "The website encountered an unexpected error. Please try again later.", and the website is ko.
I tried 4 different times also disabling every "no core" modules. No results.
Some ideas?

Thanks

Some developers have no problem following the Drupal 8 paradigm while others seem stuck with an old mindset. ie. I setup my CKEditor environment to allow interfacing with the font plugin. This screen recording I put on youtube as part of a project is an example of a getting a desirable Drupal 8 result. However, perhaps you don't see it that way at all. I've been asked to produce a book about Drupal 8 from my perspective. So any points of view are welcome.

I'm newbie in Drupal 8 development. Making some tests with this core version, I have to set an internal url that redirects to a add content type page:

$url_add_test = Url::fromRoute('node.add{type}');
$internal_add_test = \Drupal::l(t('Test Vacations'), $url_add_test);

I would like to know the "{type}" for test content and if I'm writing the sintax correctly.
Thanks.

Hi, try to crate Twig Template for my custom Block, but it not working(

Twig Template naming conventions said:
For example, "block--block--1.html.twig" would be used for the first user-submitted block added from the block administration screen since it was created by the block module with the id of 1.
