Installing Drupal

I’m brand new to Drupal, and to web development/hosting as a whole. I’ve had some experience maintaining Wordpress sites but I’m looking for a new challenge. 
  I started a new consulting company and registered a domain and hosting with Namecheap. 
  Namecheap hosting doesn’t come with softacular for Drupal so I manually installed.
  All the Links are getting a 404 error. I checked and .htacccess seems fine. Any other suggestions?

While trying to install Drupal 9 with Mysql 5.7.30, PHP 7.4.12, windows IIS on my local machine (Windows 10) getting the below error.

Drupal\Component\Plugin\Exception\PluginNotFoundException: The "user_role" entity type does not exist. in C:\inetpub\wwwroot\drupal\core\lib\Drupal\Core\Entity\EntityTypeManager.php on line 150 #0 C:\inetpub\wwwroot\drupal\core\lib\Drupal\Core\Entity\EntityTypeManager.php(269): Drupal\Core\Entity\EntityTypeManager->getDefinition('user_role')

Does Drupal 8 support having PostgreSQL13 as the backend on Linux? Are there any special php - or other - requirements when (hopefully) using this version of PostgreSQL?

Thank you.

I hope to have a very simple question about the best method to install Drupal 9 on a production server. I've browsed some of the topics and searched but can't seem to find a concrete answer. Installing Drupal 9 locally I have no problems. I use Docker. 

Installing Drupal 9 on a production server that has Softaculous is even easier. But I'm now dealing with another web host that doesn't have Softaculous. I could manually install Drupal 9 using FTP but that would take a long time. 

Hi,

I'm working on a development install of Drupal 7. It needs to be Drupal 7 to mimic a production D7 site we have now. That will be upgraded later.  

I have tried so many times and cannot get my Drupal 8 site to install.

I have put in the php.ini and .user.ini files to take care of the timezone as Europe/Berlin, but have one puzzle. When it comes to entering the site details country is required, and it is not possible to enter "Europe", so I'm wondering how I cope with this? It just doesn't seem to make sense to me.

Everything else is correct, mysql version is greater than required, I'm running on php7.4 and I believe that the PDOextension is enabled.

Can anyone help?
