I am friendly with Drupal 7 but Drupal 8 makes me sick.
I have two big problem and I think that I am not alone.
I've created a view for a block but I can't see it : I have an error message : Template "core/modules/views/views-view-fields.html.twig" is not defined ().
The other problem is the upload and display of the pictures with CKEditor. Nothing appears. My PHP config is ok. With Drupal 7, everything was OK. In the block, same problem, no pictures. Everything that I've tried NO picture appear in my website.
Please help me I am going crazy !
