Customizr wordpress compatibility??

Hi,

I’ve just installed the Customizr theme on a fresh wp install version 3.8.1. Great theme btw..

I wanted to remove the ‘Designed by Theme&Co’ (sorry guys, I know I should have kept it :)), so I adjusted the ‘class-footer-footer_main.php’ (in child-theme) file by changing the relevant values to my own (Code and changes below). However, when I did this, I got a ‘fatal error: could not change class TC_(can’t remember the middle bit)/customizr/function.php’. I couldn’t get into my site at all, front or back and my host provider had to disable for me to get back in. They suggested it could be a compatibility issue..

Is there any known compatibility issue or have I just been done over by a lazy tech support? ?? Or did I simply just get the code wrong perhaps??

Code before:

echo apply_filters(
    		'tc_credits_display',
    		sprintf('<div class="%1$s">%2$s</div>',
	    		apply_filters( 'tc_colophon_center_block_class', 'span4 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="'.TC_WEBSITE.'">Themes & Co</a>'

Code after :

echo apply_filters(
    		'tc_credits_display',
    		sprintf('<div class="%1$s">%2$s</div>',
	    		apply_filters( 'tc_colophon_center_block_class', 'span4 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://mywebsite.co.uk">MyName</a>'

I love the theme and would really like to have it back. Can anyone help on this one??

Cheers..
