Hello,

I'm new  user of PrestaShop and just appointed webmaster of an existing PtrestaShop site (non-profit). I get an error message from the backoffice of PrestaShop when clicking on details for a specific customers. I do not get the same error for other customer. I have 2 questions

• where should I start looking to solve this issue ?
• How could I avoid loosing the (real) customer info. It's not a test account.

Thanks

JMiC
