This blog has been a static site since I migrated to Blogmore back in May.
Some time over the past couple of days, my hosting provider, Reclaim Hosting, must have repopulated the directory with WordPress artefacts and my landing page had become a Setup Your New WordPress site page. I managed to remove those artefacts and used the hosting site dashboard (CPanel) to uninstall the whole WordPress app. So, hopefully, this should not happen again.
