I want to add "previous" and"next" to the individual blogs since they only have the blog titles for the next and previous links. I want to keep the links and I am having a hard time using any of the solutions provided to me and they seem to make the page worse. Am I coding the information incorrectly or am I deleting important PHP that needs to stay?
This is the problem I am dealing with:
wp_link_pages( array( 'before' => '<div class="page-links">' . esc_html__( 'Pages:', 'thermal-tech' ), 'after' => '</div>', ) );
