Drupal 8.x

Good day,

I have this problem when trying to update drupal 8.6.7 to 8.6.10 by using composer. Before this I try to update manually (replace with drupal core files and folder) but get some error with DBAL module (this module need to be install via composer). For your information, I started drupal project by copying .zip core to server directory, not by using composer. So any other way to update drupal core without having an error with module?

Thanks in advance.

Facing an issue while upgrading from drupal 8.4 to 8.6. 

The website encountered an unexpected error. Please try again later.
Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "access_check.db_update". in Symfony\Component\DependencyInjection\ContainerBuilder->getDefinition() (line 1053 of vendor\symfony\dependency-injection\ContainerBuilder.php).

Hello, let me explain what I'm trying to do:

I'm using the Media core module to store images. I created a new taxonomy vocabulary named "Albums" and then I added a new field under Image media type to reference the "Albums" taxonomy, so the user can assign the images to Albums.

Looking for a little guidance here.

We currently have a site up and running Drupal (8.6.10), and for the most I can make content changes, create basic views, update the core and modules, setup users/permissions etc...

Unfortunately the project dragged on longer than ever anticipated and I was forced to launch the site before getting all the issues worked out or really having a handle on how things work in Drupal. Once we went live with the site the developer that was assisting with the project has gone silent and is no longer responding to phone calls or emails.
