back to PHP7

[GJC Web Design]

btw fixed in the VM 4 series

[macigatto]

do you mean that VM 3.8.8 do not support PHP 8?

thank you

do you mean that VM 3.8.8 do not support PHP 8?

Most probably .. from memory debugging for php8 started with the VM4 series

hello,
I have tried with VM 4.0.6
but still this error with PHP 8.
I think it is a bug to resolve.
0 - implode(): Argument #2 ($array) must be of type ?array, string given
thank you

[macigatto]

I have resolved putting a try catch to manage the error:

JROOT/plugins/vmshipment/weight_countries/weight_countries.php:245

try{
      $result[$hash] = parent::checkConditions($cart, $method, $cart_prices);
         }
         catch (Throwable $e) {
                     
                    }

Will this be updated in a new VM release?
4.0.6 10690 AIO still has the PHP8 bug.
Have to stay on PHP7 in the meanwhile....
