jekyll-seo-tag | Jekyll plugin to add metadata tags | Search Engine library

It's really a small things, but something I can't get out of my mind.

When running gh-pages locally with jekyll serve I get the "View on Github" button, but it's missing on the live page. Everything is up to date, and all files are the same both locally and live.

_config.yml

I am trying to contribute to a Github Page/Jekyll site and want to be able to visualise changes locally but when I run bundle exec jekyll serve but I get this output:

I'm trying to run bundle install using ubuntu 20.04, rvm with ruby 2.7.2, and I can't get the eventmachine gem to install. After googling for hours I couldn't find a solution that works for me. I've tried deleting the lockfile and running bundle, ruby-dev is already installed with the latest version, I've tried running bundle with ruby 2.6.6, updating bundle, updating Jekyll from 4.0.0 to 4.2.0, and no matter what I try I'm still getting these error messages I don't understand, so any help would be VERY appreciated!

Gemfile

I'm using a Azure Devops Pipeline to build my Jekyll Blog Site and to publish it to Azure Blob Storage. It has of late been working OK, but I did a new post today and it failed in the Build step. All worked Ok a day or so ago. Nb: The build is triggered by a commit to to the Devops repository. The site built OK locally.

I am trying to add code excerpts via my gists using tag {% gist 1234567 %}. But they are not getting displayed in my post. They are displayed as is. {% gist 1234567 %}.

My post is a markdown file which I am hosting using github pages with jekyll minima theme on github. So the link to the posts look like this
https://github.com//blog/.md

I added the line to include gists into the _config.yml file. Following is the code in the _config.yml file.

Update: I got fed up and re-do everything from the ground-up and it fixes itself.

I have a github pages site built with Jekyll and Chirpy theme.

Locally, it runs great.

However when deployed on Github Pages there are a few directories that return the 404 page even though the path is valid and there is an index.html file in it.

Example: https://catmandx.github.io/posts/Wgel-CTF-Writeup/ display normally https://catmandx.github.io/tags/cmc/index.html returns 404 http://127.0.0.1:4000/tags/cmc/index.html display correcly.

I have temporarily make the repo public, it's here: https://github.com/catmandx/catmandx.github.io

I have been banging my head for a few hours now. I have tried committing and pushing again to re-run Actions, manually editing the /tags/cmc/index.html file in the gh-pages branch but nothing works.

This is the _config.yml file, not sure if it helps but here:
