Module development and code questions

Im new to drupal. my website has drupal  7 installed. After one of the updates, the header and footer portion of the site is not getting displayed. How to resolve it.

Hi guys,

Is there something like a module cache for drupal, that could mess up installations with composer?

I want to install the Bootstap 3 Module on the page I'm currenty working on. After running the install command ("composer require 'drupal/bootstrap:^3.25'") I couldn't find the module in the module folder. Just the "background_image module", I uninstalled in a few days ago. After deleting the wrong module and checking the command I tried again but the outcome was the same wrong result.

Hi everyone,

I need help with a menu item I want to create programmatically through (this is a piece of extra information) a presave hook. In particular, I want to make a menu item that is a child of a menu item created by a view (in the view administration page).

Also: I listed all children of a specific menu item (that is the parent of the menu item created by the view) and, of course, it wasn't listed with the other *basic* menu items.

How I can create a menu item that is a child of the view menu item?

This is my piece of code:

The purpose of this module is to enable developers to quickly set up a system for generating electronic documents from a json feed and a docx model.

Hello Drupal community members,

My intranet site has Drupal 9.4.4 and PHP 8.1.8. Recently we had phpMyAdmin updated.  We wanted to install some modules and they didn't show up the configuration page so we decided to clear all caches. Then all of the sudden, we have the white error page " 

This page isn’t working

10.0.200.30 is currently unable to handle this request.

HTTP ERROR 500

This never happened to me before.  Not for over a year and nine months.   Is it Drupal problem or PHP problem ?

Im having a problem with some of my views only when Im using Firefox both on mac and windows. 

When I load the page the view with a grid option doesn't load and instead shows a loading icon, however if I resize the window even slightly it loads fine.

I'm using nginx web server, drupal 8.

Please could you help as I need it to load straight away. Thank you in advance for any help.
