Post installation

Hi,

I’m experiencing trouble with some sent email DKIM signature. Presented as such it’s far from drupal but webform forms is the unique variation here. Let me elaborate :

I’m hosting a drupal 10.2.2 website with webform 6.2.2 (up to date at the moment I write these lines). It is running onto an Ubuntu server I do manage. It is as well up to date.

Hi,

under: /admin/config/system/site-information it has a field for "Email address".
It says: "The From address in automated emails sent during registration and... other notifications. (Use an address ending in your site's domain to help prevent this email being flagged as spam.)"

I've been using drupal since many many years. I have a Drupal 7 website and im sure from when this is happening but when i try to edit something it takes a long time to load the content on the edit page. But the most anoying problem is when i save and the content was unpublished. I have to go to content tab to see the content table, select the content with the checkbox and click publish content from the select component to publish. Because the only way to publish content is from the list.

What is causing this problem?

I have a new local Drupal 10 site using DDEV. However, I need to use the starterkit theme and all instructions I've seen all point to the same command.

php core/scripts/drupal generate-theme my_new_theme

This would indicate that the startkit should be installed with core, but no drupal folder in web/core/scripts nor a generate-theme script anywhere in the installation.

As a non PHP programmer and as a non Twig themer I'd like to ask this:

Let's say I add a menu block in some region which is not the Primary Navigation Menu region.

It can be a menu block of the primary menu or just some custom menu. Whatever menu it is --- this menu appears vertical.

Is the CSS of a Drupal vertical menus theme-dependent or is it theme-agnostic and depends solely on Drupal core without any connection to any particular theme?

What was/were the core theme/s before Bartik and Olivero?

I didn't use Drupal 1,2,3,4,5 so I don't know that.
