Drupal 8.x

Hi,

I am hiring freelancer to get selected web pages redesigned (only a few web pages, not the entire website).

All the menus, headers...etc remain. It is basically designing the content or node.

My question is how to only clone only selected web pages? So that, I can only send him the selected pages instead of giving him the admin username and password to log into the my account?

Firstly I am a complete noob at Drupal 8, so please make things as simple as possible.

I have a Drupal site (8.5.6), tried to update to 8.6.1 but crashed the full site (thank god I had a backup).

My Problems is when I have created a view with date recur (https://www.drupal.org/project/date_recur) it shows what I want it to but it is also showing multiple recurrences of the same date.

On my site, I have checked every link and they work.

The problem is when I use a software SEO powersuite to check the site, it comes up with 977 of errors 4XX. Now when I check a page by going to a page with an error

eg

I'm still new to coding Drupal 8, and I need to display a field that has a book ISBN number that is linked to our Amazon Associate account. The ISBN is just a simple text field of 9 or 13 characters used in a "Book Page" node. The link code looks like this:

Hi all,

I have two fields, both of which display a different taxonomy vocabulary as drop downs. Is there a way for field 2 to update its values when a selection is made in field 1?

Thanks
