I know no PHP but I managed to remove the credits at the bottom. This is the file I have right now and it works perfectly.
add_filter('tc_credits_display', 'my_custom_credits');
function my_custom_credits(){
$credits = '';
$newline_credits = '';
return '
<div class="span4 credits">
<p> · © '.esc_attr( date( 'Y' ) ).' <a href="'.esc_url( home_url() ).'" title="'.esc_attr(get_bloginfo()).'" rel="bookmark">'.esc_attr(get_bloginfo()).'</a> · </p> </div>';
}
This code will remove the “Designed by themeandco” in the code, not your websites name.
The original code has the “Designed by themeandco” in the code, I just removed that line at the bottom and got it to work. This will leave you websites name in the footer. If you want to remove the whole credits, I don’t know what you would have to do, sorry.
Hope this help!
