After updating themes.php with code I copied from a forum post (link below) my dashboard , blog, and login screen are displaying: "HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request."
I now appear to have no way to edit themes.php to undo the changes. I have tried connecting through Filezilla but only get:
Error: Connection timed out
Error: Could not connect to server

I believe the code I added was the following. This is retyped from memory.
add_filter( 'woocommerce_billing_fields', 'custom_woocommerce_billing_fields' );
function custom_woocommerce_billing_fields( $fields ) {
$fields['billing_country'] = array(
'required' => false;
return $fields;
}
