This is the content of the .info.yml file.

name: Endymion
description: Drupal 8 starter theme
type: theme
core: 8.x

    - endymion/global-css

  header: Header
  primary_menu: 'Primary menu'
  breadcrumb: Breadcrumb
  content: Content
  sidebar_first: 'Sidebar first'
  footer_first: 'Footer first'

This is the content of the .libraries.yml file.

            css/css1.css: {}

I keep getting this error message:

The website encountered an unexpected error. Please try again later.

How do I fix this error?

Additional point:

Get the same error message whether I'm running locally or on a remote server (siteground)


AFAIK you should use 2 spaces to indent your YAML. It seems you either use 4 spaces or a tab.

That is the case for the libraries files as well as the libraries key in info file.

  • Everything else does look basically fine except the indentation. – Remog Sep 5 '16 at 14:06
  • I would even think that the only problem is the indentation in .info.yml file - as that breaks the parser because it's different from the rest of the file. If you use 4 spaces consistently it may work. But I suggest that you do not and stick to the coding standard which says 2 spaces. Hint: PhpStorm can format the file automatically for you ;) – Tomáš Fejfar Sep 5 '16 at 15:59
  • Thanks Tomas Fejfar. That worked fine. I'm new to YAML. In fact I'm new to all this. Trying to start a post-retirement career. Do you know anyone who wants to employ a 71 year old trainee Drupaler :-) – meyerstevenlawrence Sep 5 '16 at 21:42
  • Nope :) But nowadays no one needs to know you're 71, you can be 18 yo blonde for all I know. That's the beauty of the internet! Best of luck and huge respect! – Tomáš Fejfar Sep 5 '16 at 21:55
  • Thanks. I've successfully added CSS and jQuery to my theme. – meyerstevenlawrence Sep 7 '16 at 0:55
