Drupal 8.x

I use a Barrio SASS Subtheme Theme with Drupal 8.
I created a content type for news and a views list to display the news wit ha teaser text and a read more link.

The problem is that if I click at a news to read the full nws it causes a white page, which is a 500er I guess, when I'm not logged in.
As admin all news are visible. It is strange that some news are also visible for guests without any error.

This behavoir is just with my theme. If I change the theme to Bartik or any other theme all news nodes are working.

I tried logging on to a site (devblog.no) too many times, and my IP address got banned (apparently permanently). What to do when I cannot log in and access the Ban module?

It should be possible to change the IP address, at the cmd prompt, entering first "ipconfig /release" and then "ipconfig /renew", but this does not work. 

I have this data and this is set to $data variable.

[
  'type' => 'app',
  'metadata' => [
    'field_application_id' => '{"value":"70001"}',
    'field_x_cient_id' => '{"value":"31"}',
  ],
  'created_at' => '2022-11-30T16:14:58.211Z'
]

I am trying to get the value of field_application_id=>value to get 70001 but not sure what would be the xpath

I can get the data using this $x_1 =  $data['metadata']['field_application_id'];  but it returns {"value":"70001"}

I recently overrided a views exposed filter by converting some textfields to select.

The problem now is html special characters won't display on screen.

E.g

Code
<option>$1,000,000</option>

Expected Display
$1,000,000

Actual Display
1000000

The '$' and ',' is removed..

I have even tried htmlentities() but no luck there.
I even tried adding the html code directly

Anybody has any idea what I should do.

Here is some of the code:

In Drupal there is a View page to make the nodes attach to the term :

/admin/structure/views/view/taxonomy_term

I need this View to show the nodes belonging to the term and its child terms.

Here is an example :

- term 1

- term 2

- - term 3

- - term 4

- term 5

I have a node attached to term 3.

If I go to the page of term 2, I want the nodes that are attached to this term or its child terms to be displayed. 

So the node attached to term 3 must appear on the page for term 2.
