Drupal 8.x

Hi everyone,

I'm new to Drupal and I wanted to add a google analytics for my site. Seems like I added the wrong one and now it removed half of the block on my site. It is not in my extend->uninstall list and I can't remove it. I didn't build the site, I'm just maintaining it. How do I fix this?  I would really appreciate any help :)

Message is:

I'm so tired of Drupal 8 composer's problem, drupal/console problems and performance issue. Is there any way to downgrade Drupal 8 to 7?

Or maybe I can export Drupal 8 nodes somehow and import them in Drupal 7?

Drupal 8 seems to be heavy, hard to manage and overcomplicated for me. I don't want migrate to Drupal 10, composer is not for me.

Thanks

I have nodes with puzzles. I store extra info on the puzzle (say puzzle_sol) in a different table. I add this extra info to node in 'hook_node_storage_load' in my module. I then attach a special library to the page in page_attachments hook. There I use the above extra info to decide whether to attach the library or not. (if puzzle_sol was added, then attach the library ... else not)

This whole strategy is working without absolutely any issue.

Now the problem.

It's a Drupal 8 Commerce site, and we just changed the shipping rate from 2,90 to 3,5€

Although the shipping rate appears just fine on the checkout/####/review page, On the checkout/####/order_information page appears the old shipping title and rate. The calculation on the cart is just fine. The wording is off though.

Let me share 2 pictures of the phenomenon. Here is the /review page: Review Page

I need to write code in a old durpal content source coding (I mean in the actual website admin content),,, which mean I can't use modules nor extensions (Too old AND using Bootstrap 4 theme). Last month, I built a carousel with Horizontal pics. NOW... The customer ask for keeping those horozontal pictures when somebody watch the original web version of the site AND/BUT he now gave me vertical pictures to create the same carousel, but to appear vertically when in mobile version.
