Read More Button

Hi there,

Try this PHP snippet:

add_filter( 'generate_excerpt_more_output', function() {
    return sprintf( ' ... <a title="%1$s" class="read-more" href="%2$s" target="_blank">%3$s %4$s</a>',
			the_title_attribute( 'echo=0' ),
			esc_url( get_permalink( get_the_ID() ) ),
			__( 'Read more', 'generatepress' ),
			'<span class="screen-reader-text">' . get_the_title() . '</span>'
    );
} );

Let me know if this helps :)
