how to remove #sthash code from url

Add this code to your child theme’s functions file, it should remove all characters beginning with#sthash on page load (if the hashes are being added frequently after load, then mention that)

add_action('wp_enqueue_scripts', function() {
	wp_enqueue_script('jquery');
});
add_action('wp_footer', function() {
	?>
		<script>
		jQuery(document).ready(function($){
		    var pageurl = window.location.href;
		    if( pageurl.indexOf('#sthash') >= 0 ) {
				var flush = pageurl.substring(0, pageurl.indexOf('#sthash'));
				window.history.replaceState( {} , '', flush );
			}
		});
		</script>
	<?php
});
