New .MD content not showing on local server

Have created a new .MD file, copied it to ../mysite/hugo-tranquilpeak-4000-theme/exampleSite/content/ , stopped the local server, restarted it, but the new content doesn’t display ?

Have also exited the browser I use (Brave) which clears all cache, cookies, etc. Same problem, new content not showing.

The new content has front matter, including both title and date.

$ hugo version
hugo v0.164.0-ce2470e7012b5ab5fc4e10ebe4027e9f8d9e00dc+extended linux/amd64 BuildDate=2026-07-06T16:39:30Z VendorInfo=gohugoio

From How to restarting the Hugo server? - Quantum Computing , the need to parse the -D flag to include draft posts. Fixed now.
