PrestaShopException trying change Category friendly URL

[renancomn]

Hi, I have a problem changing my category page friendly URL.

When I try to update shows up the message below:

 

[PrestaShopException]

Property Category->date_add is not valid

831.
832.             $message = $this->validateField($field, $this->$field);
833.             if ($message !== true)
834.             {
835.                 if ($die)
836.                     throw new PrestaShopException($message);
837.                 return $error_return ? $message : false;
838.             }
839.         }
840.
841.         return true;

I have tried the solution indicated in this topic http://www.prestashop.com/forums/topic/252976-solved-cant-save-any-chance-in-bo-to-the-categories/?hl=%20prestashopexception%20%20property%20%20category#8208 but not worked. Keep showing that message.

My prestashop version it's 1.5.2 - www.donacoelha.com

 

Any thoughts? Help me please.
