Drupal 8.x

I've recently inherited a Drupal site after our previous developer left. He didn't keep exhaustive notes and is currently unreachable.

I've managed to get access via SFTP, and located, modified and re-uploaded the files that required changes. The files were page--front.html.twig and style.css. They both have clear and profound changes, that do not show on the live site.

Should these files show immediately following changes, or are there extra steps necessary?

Hi Developers,
I am using Drupal 8.3.4 and sucessfully built my site now i am looking to add schema to all my webpages of my site
Its only showing schema on home page but i want on all the pages what i could do to show up schema on google rich snipping test tool or structured data tool so that my schema detects i have designed all my pages now i need help in showing its schema help me out developers on this.

I've come across this error a few times, and so far I've just worked around it, as I couldn't find any solutions for it online. But maybe I should ask about it. Not sure if there's a better place to bring it up. I don't know if this is a plugin problem or a problem in core... or how I might avoid it in my settings.

I am installing Drupal to create a single instance of a new website on my local Windows 7 PC under XAMPP. One of the Drupal instalation screens, I think the third, asks for the site name. Which of the following three formats can, or should, be used:

One Woman Training (three words title case with spaces)
onewomantraining (all one word and all lower case)
OneWomanTraining (one word with Camel case)

After the site is setup, can this site name (whatever it is) be changed?

Thanks,
Richard

(I just posted this under the book entry, then decided to make it a forum posting as well.)

I've just started working my way through the book and I am already confused. The publishing date says "First Printing: January, 2017" so I would have thought everything would have been verified by then.
