Class "JResponse" not found

[Gomad]

Hello

Joomla4 version 4.1.5 using actual latest VM 4.0.2

Having the "Show the pdf view icon" function enabled in the frontshop trying to get a pdf of the product page the result is: 0 - Class "JResponse" not found

How to solve this?

Being logged in the front end as superuser in a product page clicking the button "modify this product" the result is: 0 - Call to undefined method Joomla\CMS\Router\SiteRouter::setMode()

Thank you
best regards

Please enable your joomla debug. You can configure the debug plugin of joomla so, that only superadmins can see it. so you can hide it from customers.

I dont know, but with joomla debug enabled, you should see the backtrace,... just post this backtrace for both cases, then I can what is actually calling the JResponse and the setMode

Alright. Thank you.
Added a fix, just open the file components/com_virtuemart/virtuemart.php and set there an "if for j3/j4"
Just use the code below and replace the lines 72, 73.

Code Select Expand


if(JVM_VERSION<4){
$router = $app->getRouter();
$router->setMode(0);
}


It is just for the manger mode in FE. Maybe you get now other problems in the FE manager mode. But the url should just not be routed and there are no routes defined and so it should work in j4. I think that was differen in j3, it was always doing fallback routings.

Hi, I test J4 for now and I can enter edit from front page product after these fix so hooray (never use front edit personally but is good to know working now in J4)

As for PDF view i get
