I copied single-question.php template into my theme’s templatedir/anspress directory. As soon as I do that, a single question URL displays the contents of the question; however, there is no CSS styling AND the framework of my website is gone (e.g. no header, menus, footer).
UPDATE: Instead of copying the template into my themes/enfold-child theme, I copied into my themes/enfold directory. This works. But, putting it into the directory of the child theme doesn’t.
