website down after modify extra.php

Hi, I tried to get rid of “Theme by Colorlib Powered by WordPress”, I followed this thread

I did the following

Go to extras.php
There you will see
/**

  • function to show the footer info, copyright information
    */
    function activello_footer_info() {
    global $activello_footer_info;
    printf( esc_html__<>( ‘Theme by %1$s Powered by %2$s’, ‘activello’ ) , ‘Colorlib‘, ‘WordPress‘)</>;
    }

And change the Theme etc. with something like this

/**<p>Copyright © 2016 · All Rights Reserved · My Website</p>

Now my website is completely down, it says to following…

The www.dailysurprises.co.uk page isn’t working
