WordPress blog post shows up (visible) but when clicked gives error message
Clicking on post gives 404 error
After the mega destruction ("killing") of unnecessary processes, the blog came back but posts when clicked gave error messages.
That's because during the fiddling to check the problem, the .htaccess file had been renamed .htaccess.bak and something else had been created, instead.
Solution: get rid of the new one and revert the old one.
Everything came back like a breeze.
