Depending on your theme customization, you could try to add this in function.php
file located in your active child theme or theme:
function custom_excerpt_more($more) {
global $post;
return '<a class="moretag" href="'. get_permalink($post->ID) . '">' . __("Your Read More Link Text", "your_theme_slug") . '</a>';
}
add_filter( 'excerpt_more', 'custom_excerpt_more' );
WP codex: Customizing the Read More
Find corporate-plus/acmethemes/hooks/slider-selection.php. Go to about line 109 and change this code:
"Know More" - change to whatever you want. Change a href="" to a href="your-link"
