Drupal 8.x

Hello
I am having an issue of embedding google maps to the body field of block, whenever i try and copy/paste the code which is iframe, nothing happens, i tried everything, using full html hitting source before saving doesn't works either, i have tried everything and nothing seems to work, any idea or anyone else is experiencing the same problem?

Thank u in advance

I've got a custom module that takes the email address from a form and inserts a link in the email handler (via a token) that when clicked on goes to another webform and when submitted sends the reply to the original email address. 

What I'm trying to do is pass the submitted values from the first form in to this link but it's not working:

This isn't quite as simple as it sounds, let me explain below:

• User A fills in webform "Get offers" that has custom code (below) that attaches the User A email to a link via a token. 
• This sends an email to User B that has a link that sends them to webform "Provide a quote". When they submit the form an email, using the custom code, is sent to User A. 

What I'm struggling to do is get a page (using views) i.e. "My offers" where User A can navigate to to see the response from webform "provide a quote". At present, they just get the email. 

Set up :

Mysql : MYSQL v.5.6

Drupal : Drupal core 8.8.4

PHP : 7.2

Hi Drupal community,

I've recently had to migrate a drupal website from a server to another. I installed a new drupal core on the new web hosting server and I've uploaded my DB backup to the new DB. 

The problem I encounter right now is that the Drupal website is completely empty. When I say 'empty' I mean that no content is available even if the database has been well dumped.

You can refer to the following screen shot to better understand the situation.

I have a knot and there is some text in the body. After this text I would like to display from 1 to 4 links in relation to the roles of the connected user.
Is it possible to do it? how?

I'm a new Drupal user (though decades of other dev experience) looking for advice on best practices.  I need to develop a multi-client web application with defined (but client-extensible) data model, along with forms for managing data entry and API endpoints to use that data.   Basically I need to build an entire web-app that can be deployed multiple times to different independent clients, but still allow them to take upgrades and bug fixes.
