Drupal 8.x

I've been working with Drupal since 2007 and this is an ongoing pain point so I'm curious – if Wordpress can do it, why can't Drupal?

A theme is a collection of files that define the presentation layer. You can also create one or more "sub-themes" or variations on a theme. Only the .info.yml file is required, but most themes and sub-themes will use other files as well. This page lists the files and folders that are found in a typical theme or sub-theme.
Location of themes
You must place themes in the "themes" folder of your Drupal installation. Note that Drupal core themes such as Bartik and Seven are located in the core/themes folder of your installation.

Hello,

Working with our Drupal 8 site, I have noticed that when I exceed a certain number of fields I get the error message in chrome "The website encountered an unexpected error. Please try again later." or get an HTTP 500 Error in Internet Explorer/Edge.

I get these error messages when navigating the site. Once I go into Admin, it is working fine. Also from the Admin Side, if I select Content, I get the same error message. Once I delete the field from the content type, I can then now navigate the site.

I installed Drupal 8.1.7.

It runs behind a Varnish 4 cache.

I want to get ESI working.

I started looking for docs re ESI.

The obvious module

ESI: Edge Side Includes

has no Drupal 8 support

This post implies that BigPipe, ESI & Dynamic Page Cache are different things

Drupal 8 Module of the Week: BigPipe

I recently installed Drupal 8.1.7. I just installed the zurb foundation v6 theme module.

I'm about to create a subtheme. In Drupal it's a slightly different process than I'm used to. I usually start with a generic, barebones upstream theme, and build 'up'.

The README describes both the 'auto' install

drush fst myname

and a 'manual' process.

Hello All,
I am new to the Drupal world, and I am making a website for my summer internship. It was not made clear to me when I started that my organization has not migrated their sites from D7 to D8 yet, and don't plan on doing so in the near future. So, it is up to me to figure out how to convert my website that I made on Drupal 8 BACKWARDS on to Drupal 7.

I've looked into the bundle copy module but cannot figure out how it works on Drupal 8.

Somebody please help me! Thank you!
