(1) The featured image is not appearing.
(2) The default menu freezes. — I’ve discovered I can unfreeze it by reloading the page. — It took me a bit of time to figure out I needed to reload the page to “unfreeze” the menu … So the UX could be better
(3) The site Tagline does not show.
Firstly Make child theme & include single.php in your child theme.
For showing featured image,add this code in single.php
<?php the_post_thumbnail();?> (before content)
Include also header.php in your child theme:
For tag line: Go to header.php:
find this: <h2 class=”site-description”><?php bloginfo( ‘description’ ); ?></h2>
This is in comment i.e like that: <!–<h2 class=”site-description”><?php bloginfo( ‘description’ ); ?></h2>–>
remove <!– from starting & this from ending –>
Save & then refresh your site.
