Hi Mahfuddin, it’s sadly not a feature in the theme right now, however you can add it yourself by replacing:
<?php
the_excerpt( sprintf(
wp_kses(
/* translators: %s: Name of current post. Only visible to screen readers */
__( 'Continue reading<span class="screen-reader-text"> "%s"</span>', 'flatmagazinews' ),
array(
'span' => array(
'class' => array(),
),
)
),
get_the_title()
) );
wp_link_pages( array(
'before' => '<div class="page-links">' . esc_html__( 'Pages:', 'flatmagazinews' ),
'after' => '</div>',
) );
?>
with
<?php the_content(); ?>
It’s important for me to say that I don’t recommend you make changes to the theme, it can end up crashing your website if done wrong, I recommend that you hire a cheaper developer from Fiver or Upwork to help you make the changes you want to the design
I hope that answers your question, otherwise let me know!
