How do i remove Business feeds Shortcode fatal error

This is probably the issue:

$currency = wp_remote_get($current_ping);
if($currency){

$currency will either be a WP_Error object or an array. Checking if($currency) will be true in both cases.

Instead, you should check if it’s an array and not an error object:

if ( is_array( $currency ) && ! is_wp_error( $currency ) ) {

of course, that won’t fix the fact that wp_remote_get returns an error…
