Upgrading Drupal

Following https://www.drupal.org/docs/upgrading-drupal/upgrading-from-drupal-8-or-...

Note: zurb_foundation has been patched for D10

Drupal 9

I added a customized content type: product

This content type has two fields: Title and Price

Then I added the following extensions before configuring REST ui and enabled get method.

Does neither belong to D-update nor to drupal at all (I am afraid), so sorry, if wrong forum. However:

I updated php to version 8.1 and switched from mod-php to php-fpm (listening on localhost:9000) on my debian bullseye installation. Everything worked smoothly and though my Drupal installation works as expected in general apache is now blocking access to ../admin/reports/status:

client denied by server configuration: /var/www/city_eu/en, referer: .../en/admin/reports

:(. I have absolutely no clue where to look, so TIA for any hint.

Dear friends, 

There is a problem with the Drupal 9.4.5 upgrade to 10.0.2 version through composer2, version PHP 8.1 or 8.2 - I have checked both options. 

Use the command: composer update "drupal/core-*" --with-all-dependencies

And after that appears to communicate: 

I'm increasingly running into the problem where modules just won't update. I use composer so I use a command like "composer require 'drupal/slick:^2.7'". Composer appears to upgrade the module. I update the database and flush the cache. When I go back into Drupal (9, BTW) and re-run the update, it shows that I haven't updated several modules. If I try to do a composer require again, it says there's nothing to install or update. Right now I can't get slick, external links, fullcalendar view, slick carousel, or devel to update. Is it something I'm doing wrong? How can I fix this?

On Xampp I have composer, but at my hoster I have a package without composer;
so I installed Drupal 10 with their installer. 
When 10.1 came out I asked them how to upgrade it and they referred me to this Drupal instruction:
