Hi I’m looking at it.
First, thanks a ton for the detailed request… illustrated captures, all the needed links, if every request was like that Love it.
Second: what a site! Quite some work! Kudos. I see that you too must be interested in a multilingual support (I am too)
Now when I open the blog post tpl in the designer, here is what I see, when I select the category button:
I see that it is linked to the current post.
And if I change it to “Category” (not “categories template” like in your capture, which I don’t see as an option), I am actually well directed to the Motivational category page when I click the button, as expected I presume.
It’s a bit confusing, I don’t know how you end up with those links. I hope my demonstration can help you figure this out.
