Prestashop version:1.5.6.2
I didn't do any change before the problem happen.
Suddenly,in my back office,each orders by customers generate duplicate orders,two orders are same and generate the same time.
I checked the apache error log,there's no record about this.
i follow some director's suggestion,i have actived the debug module,it shows like this.
Strict Standards: Declaration of paybox::validateOrder() should be compatible with that of PaymentModuleCore::validateOrder() in /var/www/classes/module/Module.php on line 919
The first,we think it's paybox's problem,but after i contact with their service,they checked some details,they think it's not their problem.
So,i hope somebody could give me some suggestions.
Thanks.
