Drupal 8.x

I have a vocabulary TAG and common,speak and write are the terms listed.

Now when the user writes an article and he can tag the article with any of the above 3. So individually the url for those terms would be taxonomy/term/1 or 2 or 3. 

When I want to display all the articles of type common, I would use the above url. But my scenario is different.

There is an existing URL - www.example.com/prepare/common

In the TWIG template of my stores, I can render the address with the following code :

{{ store.address }}

How can I return only the postal code ?

Is there a tutorial somewhere that will help me get SSO set up for a Drupal 8 site?

I need to have Drupal registration that signs you into Moodle as well. I'm brand new to SSO so I don't even know where to start. Any tutorials would be great.

Hello,

This is my first time setting up an ubercart site. All seems to work well but the change order status or view order details gives me "Page has encountered an unexpected error. Try again later".

I have no idea what is wrong.

Is there any chance you guys could help me?
