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
