SQL error with 'pordering' column

[spinoops]

Hi,

When I update my product's second language for the first time, I have this error :

Code Select Expand

vmError: Product store TableProducts: :store échoué Column 'pordering' cannot be null SQL=UPDATE `k6sou_virtuemart_products` SET `virtuemart_vendor_id`='1', ...

Despite this error, the product is still translated... This error only appears on my online website and not in wamp localhost.

Could you please help me?

Thanks
