Customizr 3.014 – footer credits…again

I know this has been asked before but there does not appear to be an open thread that I have seen.

I have a child theme. I have a Parts folder in it. I have class-footer-footer_main.php in there.

I amended the following to reflect the information I wanted:

/**
	 * Footer Credits call back functions
	 * Can be filtered using the $site_credits, $tc_credits parameters
	 *
	 *
	 * @package Customizr
	 * @since Customizr 3.0.6
	 */
    function tc_credits_display() {
    	tc__f('rec' , __FILE__ , __FUNCTION__, __CLASS__ );
    	?>

    	<?php ob_start() ?>

    	<div class="span4 credits">
    	<?php tc__f( 'tip' , __FUNCTION__ , __CLASS__, __FILE__ ); ?>
	    	<?php
		    	$credits =  sprintf( '<p> · ? %1$s <a href="%2$s" title="%3$s" rel="bookmark">%3$s</a> · Designed by %4$s ·</p>',
					    esc_attr( date( 'Y' ) ),
					    esc_url( home_url() ),
					    esc_attr(get_bloginfo()),
					    '<a href="https://in4m.co.nz">in4m Per4mance</a>'
				);
				echo $credits;
			?>
		</div>
		<?php
		$html = ob_get_contents();
        ob_end_clean();
        echo apply_filters( 'tc_credits_display', $html );
    }

When I try to access the website nothing happens but an error message is raised:

PHP Fatal error: Cannot redeclare class.

From what I’ve read, that appeared to be what I needed to do. Clearly it isn’t. What have I missed?

Update to the above…

The result is the same even if I just have the unedited file in the Parts folder. With the unedited file the error message refers to Line 15 of the file
