Hello,

It seems to be a bug in our theme with mobile categories only. Tyr to edit the file wp-content/themes/woodmart/inc/functions.php and replace the following code

$image_output .= '<img src="' . esc_url( $icon_data ) . '" alt="' . esc_attr( $item->title ) . '" ' . $icon_attrs . ' class="wd-nav-img' . woodmart_get_old_classes( ' category-icon' ) . '" />';

with this one

if ( $icon_data ) {
	$image_output .= '<img src="' . esc_url( $icon_data ) . '" alt="' . esc_attr( $item->title ) . '" ' . $icon_attrs . ' class="wd-nav-img' . woodmart_get_old_classes( ' category-icon' ) . '" />';
}

Kind Regards
