Hello, I need to reopen this post because I have another time this error: canonical url is not displayed in the html code.
Hikashop 2.2.0
Product->view : I have the code you post
Product->view_default: I have the code you post
var_dump($this->element->main->product_canonical); it show the right canonical url

How can I check more?
Thank you

The last version of Hikashop is 2.3.0, try to update!

Onestly, I dont want to update because was working with this version.
If possible I'd like to receive some help to figure out with this version of hikashop.

Since we did some improvements on the canonical url thing you can download our last version and compare the files to see what we changed. Or even use the new views.

Ok, now the problem is that I cannot download it because my subscription is ended.
And because this function was running since the version 2.1.1(as you can read my previous posts, was really running), I cannot understand why is not more running and I need to update.

Well in this case if you still have a package of the 2.1 version you can downgrade to this one.
