Post won't appear on local and gh-pages

Help
1

I have a website at https://funeoz.github.io/techlovers and before my posts were appearing correctly when I pushed them.
But now, I finished a post. Pushed it in github. It appears in my repo at github.com/Funeoz/techlovers but doesn’t appear on gh-pages and on local when I do bundle exec jekyll serve.

I need some help.

I did a correction. It was just a a code block not correctly closed.
