Drupal 8.x

I'm a communication trainee, I have only worked with webdesign, I'm not from IT, so this is really really new to me, so I'd be very thankful if you guys could give me a step-by-step explanation, since I haven't been able to understand other guides.

The IT team told me to install Drupal 8 with xampp and postgresql, and I have managed to do it (I tried to reinstall it, thinking something had gone wrong in the process and it said I already had Drupal running). The problem is: when I type localhost/drupal I get Page Not Found.

Hello,

I successfully migrated D8 site but I get this error when I visit the site. I googled but could not find any details. I am not sure where to start to debug. Please advise!

Hello community, 

I just installed a clean Drupal 8.9.3 and Drupal Commerce 8.x-2.20 and I set 2 languages (French & German). 
I created a new product translated for both languages (title & body).
When I went to the product page (fr/product/1 or de/product/1) translations are OK but when I added the product to the cart and I checked the list of product (de/cart) product name and product URL are always in french (the default language)

Do you know if I have a possibility to change that ? Or it's a known problem ? 

Thanks a lot for your support

Hi, I want to make a very simple custom module for users to send email invitations with templates.

Here is a module that I started :

https://git.drupalcode.org/sandbox/zenimagine-3170712/-/tree/main

Currently this module creates a blank page /user/ID/invitation

How to create an "Email address" field and a template selector ?

The "Email address" field must not keep the addresses in the database.

I am using Heading module https://www.drupal.org/project/heading it basically two fields widget one is text box(drupal core textbox) where user can type the text and second is dropdown where user can select the heading type.

now issue is that drupal core text box having limit 128 characters i want to increase the size. i already have the data in this field kindly guide me how can i do that

So there is this good module :https://www.drupal.org/project/webform, which let me create forms, i want to save these forms in my site , and i want a search engine api ( a module maybe?) that is related only to these forms, so if i search something related to forms, it should show all forms related to it, for example in form i have ``company name`` and let say the company name is :drupal, when you search drupal in the search engine, it should show all forms that has drupal as the company name.
