Child theme, I am placing some theme files in it, but they are not over-riding

The child theme will override only the template files i.e. which generate some html on the website. The func.php file contains the functions and functions cannot be overridden like this. There are hooks i.e. actions and filters which can be used to make changes in the functions. If there is no action or filter available in the function then it cannot be overridden.

For this you just need to change the $link_html in the code, and there is already a filter available on this variable i.e. "wplms_registeration_page". Add the bellow code in your functions.php file of child theme.   add_filter('wplms_registeration_page','wplms_custom_login_link_non_loggedin_users'); function wplms_custom_login_link_non_loggedin_users($link_html){   $link_html = '<a href="http://www.saferelationships-safechildren.ca/sign-in/" class="link"> '.__(' LOGIN','vibe').'</a> | <a href="'.wp_registration_url().'" class="link"> '.__(' REGISTER NOW','vibe').'</a>';   return $link_html; }
