Cart prices blank

I’ve had to put up store notice and restrict sales as my cart now comes up with no prices. Worked fine last week now prices in cart come up as 0.00.

I don’t know what caused this I did not make any changes. I’ve disabled most plugins.
This is a retail site so I did use a code in the wordpress functions to double the wholesale price but that has always worked fine.

Here is the code I used. It has been working fine for months:

function return_custom_price($price, $product) {
global $post, $blog_id;
$price = get_post_meta($post->ID, ‘_regular_price’);
$post_id = $post->ID;
$price = ($price[0]*2.0);
return $price;
}
add_filter(‘woocommerce_get_price’, ‘return_custom_price’, 10, 2);

I really need help to remedy this. Thanks in advance.
