Ok, I have found what made the error, I have implemented this code in my website:
https://tomjesch.com/display-woocommerce-products-with-and-without-tax/
function edit_price_display() {
global $product;
$price = $product->price;
$price_incl_tax = $price + round($price * ( 21 / 100 ), 2);
$price_incl_tax = number_format($price_incl_tax, 2, ‘,’, ‘.’);
$price = number_format($price, 2, ‘,’, ‘.’);
$display_price = ‘<span class=”price”>’;
if($product->is_on_sale()){
$sale_price = $product->get_regular_price();
$sale_price = number_format($sale_price, 2, ‘,’, ‘.’);
$display_price .= ‘<span class=”woocommerce-Price-amount amount”><span class=”woocommerce-Price-currencySymbol”>€</span> ‘ .$sale_price .'</span>‘;
$display_price .= ‘<ins><span class=”amount exc_btw”>€ ‘ . $price .'<small class=”woocommerce-price-suffix”> ex btw</small></span></ins>’;
}
else{
$display_price .= ‘<span class=”amount exc_btw”>€ ‘ . $price .'<small class=”woocommerce-price-suffix”> ex btw</small></span>’;
}
$display_price .= ‘<br>’;
$display_price .= ‘<span class=”amount incl_btw”>€ ‘ . $price_incl_tax .'<small class=”woocommerce-price-suffix”> incl btw</small></span>’;
$display_price .= ‘</span>’;
echo $display_price;
}
//add_filter(‘woocommerce_get_price_html’, ‘edit_price_display’, 10, 2);
And that broke the search option.
