I was adding code to my Theme Functions and my website disappeared

Hi

I have a Woo Themes theme – Freshnews- and I recently installed Woocommerce as well.

There were a couple of changes I wanted to make to Woocommerce so I asked Woo how to do it. Their answer –

Hi Elizabeth

To remove the sort can you add

remove_action( 'woocommerce_pagination', 'woocommerce_catalog_ordering', 20 );

to your theme functions file

You can remove the “required” on the address fields by copying this code

https://wcdocs.woothemes.com/snippets/tutorial-customising-checkout-fields-using-actions-and-filters/#section-5

in your theme functions file
………………………………………………

I followed the first instruction and it worked. Then I copied the code I got from the link –

<?php

add_filter( 'woocommerce_billing_fields', 'wc_npr_filter_phone', 10, 1 );

function wc_npr_filter_phone( $address_fields ) {
	$address_fields['billing_phone']['required'] = false;
	return $address_fields;
}

?>

and pasted it under the first bit of code I had already pasted in my theme functions file, but this time when I pressed Update File, my whole site disappeared.

I deleted the code I had just pasted and pressed the Update File button again thinking it would undo whatever I had just done but alas, if I move anywhere from this page it is just blank.

I did notice when scrolling down from where I had pasted the code there is a very ominous message saying “Don’t add any code below here or the sky will fall down” But I didn’t add any code below that message, I didn’t even see that message until after the event. I only added the code below the code I had already added, which was added under the words “End WooThemes Functions – You can add custom functions below”

I can’t even log into my admin, there is just a blank page so I am guessing which version of WordPress I am using.

I did search the forums and Google and there were a lot of people who’s site had disappeared but I couldn’t find any with the exact problem as mine.

Hope you can help.
