Drupal 8.x

I'm developing a complex AJAX form and it works under the core themes, like Bartik. But switching to the customer's theme brings up this error when submitting the form.

Ah, you say that clearly this theme function is goofed up. To ensure it wasn't something in my form code, I copied over the ajax_addmore from the examples project which is much simpler to walk through and debug.  I wish it were as simple as that, but in watching it go through the ajax_addmore form it doesn't bail as it goes through each of the AJAX steps. When it bails on the submit step, it fails at line 1008

According to admin web interface an update to 8.9.18 is needed.

But when I ask composer list the available updates, I can only see 8.9.16

I want to exclude "Language path prefix" from the admin screen URL of a multilingual site.

"https://hogehoge.com/ja-jp/admin/"
↓ ↓ ↓ ↓ ↓
"https://hogehoge.com/admin/"

The reason is that the page is not working on the view settings page.

Is there a way?

Hi team

I have one issue,
I've created some items for a content type on my develop site, I've created something like 30 new items and i would like to export them and import on my production site

How can i export them and import on my production site?

I've tried using Configuration synchronization but i dont know how to export all my items.

Could you please help me?

In one view I added the display for viewing the data relating to an entity reference (add Entity Reference).
In the content type I linked this view to the entity reference field and everything works fine.
I have a problem with roles.
If I do not enter the user's role in the view, the autocomplete does not work because it does not find the view.
If I enter the user's role at the entity reference view it works.
The problem is that it displays the entire view to the user who does not have permission to see the other displays

What is the best module to show the store locations on the site? I want to show the store list with map.

I tried https://www.drupal.org/project/gmap_store_locator but it doesnt shows the store list at left side with search options. It just shows the full screen map when used it as a block on any page. Although, /store-locator page works as expected.

Any help on this?

Thanks,
