Check the URL and Paths:

Ensure that you are accessing the correct URL.
Hexo may be configured to generate content under different paths.
For example, if your site is located in a subdirectory, you might need to access http://localhost:4000/subdirectory/

Missing markdown renderer

Ensure your dependencies has hexo-renderer-marked or hexo-renderer-markdown-it, or install by:

npm i hexo-renderer-marked
# npm i hexo-renderer-markdown-it

rm -rf node_modules
npm install
