Installing Drupal

Hello, I installed Drupal 10.2.3. To begin with I installed the demo of umami. I could have a look at that site, its content, and a few other things at that time. Today, a couple of days later, I am unable to access that site on localhost. I checked the addresses in the history. This was one of the addresses I seem to have visited on the day I installed the Umami website

http://localhost/drupal-10.2.3/en/admin/content

Trying install Drupal 10.2.2 on OpenBSD but get stuck with 500 Server Internal Error

was using composer and just downloaded tar.gz no luck

So get 10.1.8 and it run at least setup 

I originally thought this was an issue with the version of Drupal that Composer installs in DDEV, but it appears that even in the full core files download package there is no core/scripts/drupal folder with the theme starterkit install script. It's missing (screenshot).

Hello,

I am very new to Drupal and am going through the Aquia Academy. I am trying to install Drupal on my local environment. I am following the instructions that state to use your site name to initialize the installation. My question is where do you create the site name? I tried using the one that was used in the example but it is not working so I am a little bit confused. 

The URL that they gave was waterfallhandbook.ddev.site/core/install.php

I tried to use the site name I created in the PowerShell but it didn't work.

Using XAMPP (with PHP 8.2.12) on Windows 11, and running the installation of Drupal 8.98, there are two pages of Deprecated function warnings, followed by a fatal error:

Fatal error: Declaration of Doctrine\Common\Reflection\StaticReflectionClass::getConstants() must be compatible with ReflectionClass::getConstants(?int $filter = null): array in C:\xampp\htdocs\drupal8.local\vendor\doctrine\common\lib\Doctrine\Common\Reflection\StaticReflectionClass.php on line 109

Drupal 7 installs okay.

How do I resolve these errors, please?

I have a few D10 sites I'm working on under DDEV. However, I wanted to use the starterkit theme and all instructions point to the same command and seem to indicate that this should be installed with core.

php core/scripts/drupal generate-theme my_new_theme
