Duplicate orders and customers shopping carts

[jzylbj]

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.
