I get this error when I try to uninstall Field Layout :

I'm looking for a good solution to a problem I have. I'll try to describe it as best I can, but please ask if it's not clear.

I have nodes which contain information on videos (like title, description, etc.). I want to tag these videos (nodes) with all kinds of information, like the songs in it, the clothing someone wears, etc. I figure I can use one hierarchical vocabulary for that, as in:
- Song
-- Hello
-- Alpha
- Clothing
-- Blue pants
-- Hoody

I'll use Simple Hierarchical Select to add new terms on the node (once that works).

I am struggling with implementing a specific feature in my new website project and I'm hoping someone out there in the community can offer some guidance.

I have a Views page with a set of exposed filters for various categories/taxonomy terms that return teasers that link to the full node.

Each node has an image field with multiple values. By default in the view, I simply wish to show the first image from the mutifiield, which is fine for me to do in either the Views settings or calling {{ content.field_images.0}} in Twig.

I've been following along with Ben Finklea's book and all seemed fine. Using the Metatag module I set it up per the book for Metatag itself, Google Plus, Open Graph, Twitter Cards and Verification.

I just installed W3C Validator and ran it. It didn't like any of the pages on my site.

Here are the first four lines on every page on my site:
