Installing Drupal

I have successfully installed a new Drupal9 site with PhP 8.1 on an Ubuntu Apache2 platform using composer. I recognize the need to get off the deprecated D7 baseline but have been challenged by the introduction of many new capabilities, though I have built and run a D7 site for many years on Synology hardware. The problem I am having is I am unable to navigate from the landing page on the new site.

I uploaded zip package on server hosting, install Drupal 9, last 11 and try new 12 version too and in installation everything was okay, but after installing, page is only with text, without any graphics and menu.. Please help, I tried everything I think.. 

Hello,

I have installed a drupal 9 in my local server Apache 2.4 and php 8.1, but when I access to that the browser said me:

"Deprecated: Return type of Symfony\Component\HttpFoundation\ParameterBag::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /Users/ismaelgarcia/Sites/blog/vendor/symfony/http-foundation/ParameterBag.php on line 220"

Do you know what is the problem?

Thank

OS:  Linux 8 Stream

Database:  PostgreSQL 14.2

Drupal:  9.3.11

I originally installed 9.3.10 by hand last week, then after reading more documentation and receiving the 9.3.11 availability notice I decided I should be using Composer, so I created another Drupal instance using Composer.

Previously worked with Drupal 9.3.9 version today I tried to fresh install so I downloaded 9.3.11 It was redirecting to http://localhost/drupal-9.3.9/core/install.php then I tried old versions like 9.3.9 or 9.2.9 both redirecting to http://localhost/drupal-9.3.9/core/install.php

Server:  Centos 8 stream, DB:  Postgresql 14.2, Drupal 9.3.11

I set up my first test system a few days ago manually, then got the notice that 9.3.11 core was available.  By then I had decided I really should be using Composer, so I set up another site with 9.3.11 using the Composer installation instructions in the User Guide.

Looking at my database logs, I see errors saying relation flood does not exist.

Comparing the tables in the original setup with the new one, the flood table is, in fact, missing.
