Installing Drupal

I've been managing a few Drupal sites from the UI backend for several years, and I want to update my skills by extending my Drupal installations through Composer, as I see it’s the preferred method for installing modules.

I enabled the Media module, set up an image media type, and added a media field to a content type. However, when I click to add a file but got the error "Oops, something went wrong. Check your browser's developer console for more details."

I looked and saw the following message: 

I'm having trouble installing Drupal on my server. I've followed the installation steps, but I keep encountering issues. When trying to access the Drupal site after installation, I receive a "500 Internal Server Error". Here are the steps I followed:

I’m relatively new to Drupal and have just completed the installation of the CMS. I have an existing website built using another platform (non-Drupal), and I’d like to know if it’s possible to import or migrate the entire site into Drupal without having to rebuild it from scratch.

Specifically, I’m wondering about:

1. Content migration: How can I import existing content like pages, posts, media files, etc., into Drupal? Are there any modules or tools that can help with this?

I've just finished installing the latest stable release of Drupal by following the steps at https://www.drupal.org/docs/user_guide/en/install-run.html.  After the last step, when I tried to access my Drupal site, it looks crappy. Firefox debugger shows that it is not able to find the directories sites/default/files/js and sites/default/files/css. I looked at my directory C:\drupal\web\sites\default\files and sure enough, there are no "css" nor "js" folders under there.

Hi everyone,

I'm experiencing a persistent problem with my Drupal setup running in a Docker container using a PostgreSQL database. When I try to add content, like an article, I receive the following error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in /opt/drupal/vendor/twig/twig/src/Extension/SandboxExtension.php on line 130

Here are some details about my setup:
