Categories links in list / detail pages
I have followed the tutorial on creating a portfolio (https://docs.grabaperch.com/video/v/portfolio-with-categories/) as it is similar to what I am trying to do with a listing / detail page.
I have a couple of different layouts which utilise different prices/offers depending on if someone is a business or personal customer and for this reason they are inside separate folders for example /business or /personal.
I am trying to use categories within these folders so for business it would be /business/category.php and would like it to display a list of offers related to the category selected on the detail page. However I am having issues getting this to work when you click a category link it isnt returning the category.php layout with a list of offers in the way it does in the portfolio tutorial.
Any help would be apprciated.
