Twenty Ten – replace "Continue reading" with custom text

review this codex guide and see if it helps: https://codex.www.ads-software.com/Customizing_the_Read_More

I didn’t review the codex – unfortunately it didn’t help at all as all the examples I tried didn’t work when put into the child’s them functions.php

https://www.transformationpowertools.com/wordpress/read-more-in-twenty-ten-child-theme

looks a bit complicated, but works.

found meanwhile the following piece of code that works as well:

function change_excerpt_more(){
	   function new_excerpt_more( $more ) {
	        return '<span class="read-more"> <a href="'. get_permalink($post->ID) . '">Read more</a> </span>';
	   }
	   add_filter('excerpt_more', 'new_excerpt_more');
	}
	add_action( 'after_setup_theme', 'change_excerpt_more' );

Thanks for your help guys
