Unknown column ‘Keine’

Hi there,

it seems like there is a translation problem. I’m using the german version and my error logs show error for Unknown column 'Keine' in 'where clause' für Abfrage SELECT * FROM wp_nm_personalized WHERE productmeta_id = Keine. This should be None I guess.

The complete error:

[error] 699#699: *67098 FastCGI sent in stderr: "ugins/woocommerce/templates/taxonomy-product-tag.php'), wc_get_template, include('/themes/my-theme/woocommerce/archive-product.php'), wc_get_template_part, load_template, require('/themes/my-theme/woocommerce/content-product.php'), do_action('woocommerce_after_shop_loop_item_title'), WP_Hook->do_action, WP_Hook->apply_filters, woocommerce_template_loop_price, wc_get_template, include('/plugins/woocommerce/templates/loop/price.php'), WC_Product_Variable->get_price_html, apply_filters('woocommerce_get_price_html'), WP_Hook->apply_filters, ppom_woocommerce_alter_price, ppom_has_field_by_type, PPOM_Meta->__construct, PPOM_Meta->settingsPHP message: WordPress-Datenbank-Fehler Unknown column 'Keine' in 'where clause' für Abfrage SELECT * FROM wp_nm_personalized WHERE productmeta_id = Keine von require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/plugins/woocommerce/templates/taxonomy-product-tag.php'), wc_get_template, include('/themes/my-theme/woocommerce/archive-product.php'), wc_get_template_part, load_template, require('/themes/my-theme/woocommerce/content-product.php'), do_action('woocommerce_after_shop_loop_item'), WP_Hook->do_action, WP_Hook->apply_filters, woocommerce_template_loop_add_to_cart, wc_get_template, include('/plugins/woocommerce/templates/loop/add-to-cart.php'), WC_Product->add_to_cart_url, apply_filters('woocommerce_product_add_to_cart_url'), WP_Hook->apply_filters, NM_PersonalizedProduct->loop_add_to_cart_url, PPOM_Meta->__construct, PPOM_Meta->settingsPHP message: WordPress-Datenbank-Fehler Unknown column 'Keine' in 'where clause' für Abfrage SELECT * FROM wp_nm_personalized WHERE productmeta_id = Keine von require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/plugins/woocommerce/templates/taxonomy-product-tag.php'), wc_get_template, include('/themes/my-theme/woocommerce/archive-product.php'), wc_get_template_part, load_template, ...

Any suggestions?
