You answered this in a previous post, but that was a while ago when you said a new theme would change the situation.
I have Theme version 3.4.7.
The arrows on left and right of the page to navigate the portfolio entries click through ALL my portfolios entries in ALL categories. Is there a way to limit the arrow navigation to just one category?
You can set them to link to the same category, https://kriesi.at/support/topic/avia-post-nav-with-the-same-category/.
