Hi,
After upgrading Joomla to 5.1.1 I am getting error method_exists(): Argument #1 ($object_or_class) must be of type object|string, bool given
when trying to access Orders tab in Hikashop as per photo.

Any solution please?

Hi,

We'll need the full error message to be able to understand what's going on.
Please activate the "debug" setting of the Joomla configuration and try again. You'll then get the full error message on that page.

Thanks. This is what I got.

An error has occurred.

Hi,

Thanks ! That's exactly what I needed.
I don't that the error is linked to the update of Joomla. I think it comes from an update of PHP as well as the use of a shipping plugin for an order of your orders listing which has been disabled or uninstalled.
Change the line: to: in the file administrator/components/com_hikashop/classes/shipping.php and it should prevent this error.
We'll add the change on our end too for the next version of HikaShop.

Thanks. That fixed it.
