Product pages not showing and can't access wp-admin

It is there try following this link to a product page. Might need a refresh. I could do with your insight.

Hi Rikard,
I have tried restoring but I get critical errors. The host 123-reg say the problem is with the child theme I created for Enfold. Please can you look at my child theme functions,php code and see if it has errors. Apparently it is line 23. My child theme is called Orion I.T. Theme:
<?php

/*
* Add your own functions here. You can also copy some of the theme functions into this file.
* WordPress will use those functions instead of the original functions then.
*/
//set builder mode to debug
add_action(‘avia_builder_mode’, “builder_set_debug”);
function builder_set_debug()
{
return “debug”;
}

/* Add Custom class to all ALB elements */
add_theme_support(‘avia_template_builder_custom_css’);

/*
Woocommerce 3.0.0 Compatibility Fix
Remove Enfold’s custom functions that conflict with the new image display in WooCommerce 3.0.0
*/
global $woocommerce;
if( version_compare( $woocommerce->version, ‘3.0.0’, “>=” ) ) {
function avia_woocommerce_gallery_thumbnail_description($img, $attachment_id, $post_id, $image_class ) {
return $img;
}
function avia_woocommerce_post_thumbnail_description($img, $post_id){
return $img;
}
}

add_action( ‘woocommerce_single_product_summary’, function() {
echo ” – FREE SHIPPING IN THE UK!”;
}, 10);
