Drupal 7.x

I recently "dockerized" an old Drupal installation using the official image drupal:7.82. So far everything works except one thing:

The original installation contains one single "book", but I am unable to make it visible/editable in the Webinterface. Also, I get a duplicate key error when I try to add a new book:

QUOTE SOUGHT to fix Large non-commercial multi-author politics and environment site, originally built in 2006 by the co-owner, who was subsequently disabled in a car accident.  Huge database, lots of problems.  Maybe we need to split the contents of the site in two or more new sites - old material and recent and ongoing.  We are looking for suggestions. Needs to be brought up to Drupal 9, of course.

Hello.

Im working Drupal 7 on my localhost (Windows) and i wanted to add a diary on a path of my website.

The calendar module is not useful for me in this case because it shows a lot of days etc, and its too big.

I'm new on Drupal so I dont have exactly the way of doing it, I guess it's a View format but i'm not sure. I just want to add 3 days on the top for example:

Day 1                    Day 2                      Day 3

Hello,

I have a simple D7 page (latest Drupal version) that contains a picture block with direct URL to a sub domain jpg file (simple picture).

The block is simple code:

Hi All,

Drupal version = 7.82
Profile 2 version = 7.x-2.0
Rules version = 7.x-2.12

Filips = User 1 with Administrator role which has all permissions enabled.
TestUser = User with Administrator role and the same few other roles that Filips has so identical (except for Filips = user 1)

I created a profile with a field called T2aT2bDate. Its a normal text field without default value.

I created a simple 3 node system: Node T2 and 2 children T2a and T2b.
T2 contains 2 links: GotoT2a  or  GotoT2b.

I have a view page that shows all my products from new to old. It also shows sold items (stock = 0).
The site has been running for a couple years and it is filled with sold out items. Is there a way for me to add a filter to the view that filters out the sold out items older then for example 14 days.
I can add a stock = 0 filter but that removes all of them. I can add a filter that filters all products older then 14 days but that is also not what I want. I need to combine these 2 and I can't figure out how. I tried with the AND/OR function but that didn't work.
