Hi,
Then it means that you're not removing the CAD like you should. In the currency options, there is the format option where you can change the display of the currency to use the symbol instead of the code as explained in the documentation:
www.hikashop.com/en/support/documentatio...ncy-form.html#locale
If you remove the code from the currency, the currency won't be accepted anymore by PayPal and the PayPal plugin will disappear.
For the "each" word, as I said, you can remove it with a translation override of the word. That can be done in the Languages tab of the configuration of HikaShop as explained in the documentation link I gave you.
If there is an error regarding warehouse configuration, it means that the options of the plugin are not set properly. I can't say exactly what it is without looking at what you did. Could you post a screenshot of the options of the canada post plugin ?
