How to change read more text in Hestia

If you have not created a child theme then be sure to create one before proceeding or your changes will be lost on next update: How to create a child theme

After you have created your child theme add the following snippet to change the text:

function hestia_excerpt_more_new( $more ) {
	global $post;
	if ( ( ( 'page' === get_option( 'show_on_front' ) ) ) || is_single() || is_archive() || is_home() ) {
		return '<a class="moretag" href="' . esc_url( get_permalink( $post->ID ) ) . '"> ' . esc_html__( 'Continue Reading...', 'hestia-pro' ) . '</a>';
	}
	return $more;
}
add_filter( 'excerpt_more', 'hestia_excerpt_more_new', 20 );

You could change the text to your liking.
