How to fix this error [PrestaShop\PrestaShop\Core\Domain\Customer\Exception\CustomerException code 0]

[Simon Lee]

Hi,

I am using Prestashop 1.7.6.5. In the Backend, I created a new customer group and tried to assign a customer to this new group. When I clicked "Commit", it showed the following error:

An unexpected error occurred. [PrestaShop\PrestaShop\Core\Domain\Customer\Exception\CustomerException code 0]

How can I fix this? Please advise. Thanks.

Regards,
Simon Lee

I found the solution in the forum:

For anyone having problems with the "[PrestaShop\PrestaShop\Core\Domain\Customer\Exception\CustomerException code 0]" error, I've just been experiencing that whilst trying to change customer details, passwords etc on PS 1.7.6.2

This was due to an upgrade from an older version and the "date_upd" column in the ps_customer table was set to "0000-00-00 00:00:00" for some customers, and that was causing the issue.

As a quick fix, for any customers with a blank date_upd column, I copied the value of the date_add column with an SQL query:

UPDATE ps_customer SET date_upd = date_add WHERE date_upd = '0000-00-00 00:00:00'

right

or below for all customers into DB if the query give error when filtering only customers with a blank date_upd column

UPDATE psiw_customer SET date_upd = sysdate()

I got the same error trying to delete a language entry but I have no user with date on 0.

When I executed this command, the problem was solved.

sudo chmod -R 777 .htaccess

And if we run the shop in a local envoirement like Xampp for Windows, how do we do that?

In Windows, It's not required. 

Files have permission by default in the windows.

I didn t know that. Thank you!

I thought ZHSoft solution will work for me too but it seems like I have bad luck
