BillyNoah, thanks for clarifying those issues.
I was making the changes to this file:
Code: Select all
catalog/controller/product/product.php
But I did think that it couldn't be a bug in those files- otherwise other people would be getting these errors too.
Looking through the xml files, I have just realized that it must be this file I should be editing:
Here is the code for that file:
Code: Select all

I would really appreciate it if anyone could take a look and see what needs changing.
Thank you
