To override “Designed by Press Customizr” link, put your custom credits inside the $credits variable (line 3).
To add a new line of links (Terms and Conditions, Confidentiality, etc…) put them (as html) inside $newline_credits variable (line 4).
Input your html (as instructed above) in the code below and add it to your child theme’s functions.php:
add_filter('tc_credits_display', 'my_custom_credits', 20);
$credits = '';
$newline_credits = '';
<div class="span6 credits">
<p> · © '.esc_attr( date( 'Y' ) ).' <a href="'.esc_url( home_url() ).'" title="'.esc_attr(get_bloginfo()).'" rel="bookmark">'.esc_attr(get_bloginfo()).'</a> · '.($credits ? $credits : 'Designed by <a href="http://www.presscustomizr.com/">Press Customizr</a>').' ·'.($newline_credits ? '<br />· '.$newline_credits.' ·' : '').'</p> </div>';
Note: Since you received this beautifully designed theme for free, please have the courtesy not to write “Designed by ” in your custom credits, especially if your contribution to its looks would better fit in the “Customized by” section. A few suggestions: Developed by * / Made by * / by * / Produced by * / web-dev: * or (who not?) Customiz’d by * (where * would be your link).
Note: functions.php of your child theme is NOT supposed to be a modified version of its parent theme counterpart. If unsure, please find out here how to add a child theme.
