sisqonrw on "[Plugin: WooCommerce - excelling eCommerce] error on Variation Details on Page Product"

hi i get this error report in my shop:

http://www.komili.eu/?product=komili-creme-shampoo-mit-olivenol-fur-normales-haar-700ml

error:

"Warning: implode() [function.implode]: Invalid arguments passed in /home/komilieu/public_html/wp-content/plugins/woocommerce-variation-details-on-page-product/wc-attributes-on-page.php on line 87"

whats wrong here?

This is what is in line 87:

$return[] = 'weightValues = new Array ("' . implode( "\", \"" , $attributs_weightValues) . '")';
