So everything else works? Products name? the image is showing up on FB? etc?
For the price you could try changing line 144 (of update_product.php in admin/includes/modules) where you see:
PHP Code:
$price = $products_price;
to:
PHP Code:
$price = $_POST["products_price"];
As for the discription, I'm not sure. Are there any special characters in the discription?
Maybe try changing line 147 where you see:
PHP Code:
$prod_description = implode(" ", $_POST['products_description']);
to:
PHP Code:
$prod_description = $sql_data_array["products_description"];
Let me know if that helps
