VAT number is empty

[HAIRWEBSHOP]

Hello,

 

I've set VAT as a required field for the customer address, if I enter and save a valid VAT number, Prestashop crashes showing the following error:

 

[PrestaShopException]

Property Address->vat_number is empty
at line 909 in file classes/ObjectModel.php

904. }
905.
906. $message = $this->validateField($field, $this->$field);
907. if ($message !== true) {
908. if ($die) {
909. throw new PrestaShopException($message);
910. }
911. return $error_return ? $message : false;
912. }
913. }
914.

Can someone please help me figure this out?
Thank you in advance!

PrestaShop version? Is this happening in the front? Custom theme?
