is this a default prestashop or upgraded from 1.6 or older 1.7 to 1.7.8.0?

[Fall-]

Hello,

Is default prestashop 1.7.8.0. Is not upgraded.

Here is the code from product.php line 7141. 

       }

        // result is indexed by recordset order and not position. positions start at index 1 so we need an empty element
        array_unshift($result, null);
        foreach ($result as &$value) {
            $value = $value['id_product'];
        }

@aruiz0922, In my case the issue was a field that was valued as boolean while it was supposed to be an integer. In this situation on the array returned you should be able to view the errors as well.

[aruiz0922]

Thanx for the response.

In my case the error comes while getting some blank schemas about 15 of them. Think I'm goin to make a new post for my problem

Hello aruiz0922,

Have you found solution for errors with blank page ?
I upgraded to lastest version and I've got the same problem.

If your problem comes while getting the blank schemas, my solution was to download the blank xml schemas to a folder and read the schemas from there.

Hi,

I have same problem (Prestashop 1.7.8.8, PHP 7.4.30) on line 7149 of /classes/Product.php.

A solution is to change the line like this:

$value = (isset($value['id_product']) ? $value['id_product'] : null);
