Cart problem

I am updating from J3 and VM3 to J4 and VM4.0.12.

Normally I use the OPC extension from Rupostel. When hitting the place order button, I got the error: Call to undefined method Joomla\Database\Mysqli\MysqliDriver::query
I think something wrong in one of the extension files, so I have reported this to Rupostel.

But switching of the extension and using the default cart checkout from virtuemart, I get the following order after hitting the place order button: "Class "JDispatcher" not found ".

Anyone an idea what is wrong?


Any other 3rd party plugins? Such as Advanced Shipping by Rules?

Please mention your VirtueMart, Joomla and PHP versions when asking a question in this forum


ah, thank you for pointing me in the right direction.

It was caused by the "Advanced Ordernumbers for VirtueMart" plugin from open-tools. Old extension I used, but it is not compatible and is no longer maintained
