Mauvaise Requête Sql Column 'date_Add' In Where Clause Is Ambiguous

[HectorMegnor]

Hello,

 

In prestashop's back-office, when you go to Clients->Garanty Customers, select dates under Registration and then click on the filter button, I get this :

 

Mauvaise requête SQL Column 'date_add' in where clause is ambiguous

 

I tried to find it in the databases and there's 'data_add' column in  these tables : rv_group , rv_log , rv_manufacturer , rv_message , rv_message_readed , rv_orders , rv_order_history , rv_order_message , rv_product , rv_sekeyword , rv_statssearch , rv_stock_mvt , rv_stock_mvt_reason , rv_supplier , rv_address , rv_cart , rv_cart_product , rv_category , rv_cms_category , rv_configuration , rv_connections , rv_connections_source , rv_customer_message , rv_customer_thread , rv_discount .

 

The page has these columns : ID , Title, Last name , First Name, Email address, Age, Enabled, News. , Opt. , Registration , Transporteur, Qualité, site d'achat, date d'achat.

 

I have spent time looking for it in the code and still can't find the solution.

 

Cheers,
