If you’re having a single Product or Service, you may not need a showcase page for displaying Products and Services. Instead you may need to directly showcase all your Knowledge base Categories.
To do that,
Create a new page and put a unique title to the page for example “WPH Categories” and select “WPH Categories (Single product mode)“ Page template under “Page attributes” on the right hand side as shown in the screenshot. And publish the page.
If you’re using the system in Multiple product mode, then this step is not needed. It means, you don’t need to create front page for Categories because the system will show the selected categories automatically when clicking on a product from the front page.
