Upgrade to 1.6.1.0 from 1.6.0.1 Employee First name invalid

[3cxonline]

Could someone help we have recently decided to setup a new eCommerce site using Prestashop I am inexperienced with prestashop and have thus far been impressed but will need newbee responses but I am technical.

 

I just used the one click upgrade to upgrade our shop to 1.6.1.0 as we were having another issue with localisation. That aside after upgrading when we click on the dashboard or try and edit a Emploee from Administration > Employee I receive an error 

 

"The firstname field is invalid."

 

When on the Dashboard I the error is more extreme

 

 

 

[PrestaShopException]

Property Employee->firstname is not valid
at line 881 in file classes/ObjectModel.php

876.
877.             $message = $this->validateField($field, $this->$field);
878.             if ($message !== true)
879.             {
880.                 if ($die)
881.                     throw new PrestaShopException($message);
882.                 return $error_return ? $message : false;
883.             }
884.         }
885.
886.         return true;

The issue in my case was that the administrator had an "invalid" firstname, it contained a foreign character. I changed the firstname in the database in the  _employee table to an all english name. It solved my issue.
