The theme does not interfere with the default sorting of categories by WordPress in any way. To introduce a custom order of categories in WordPress you could use the Intuitive Custom Post Order plugin. Once you install and activate the plugin, please go to “Settings” -> “Intuitive CPO” in your Admin Panel and select the taxonomies that you’d like to order (e.g. post categories). After you do that you’ll be able to go to to “Posts” / “Categories” and just drag and drop category names to reorder them.
hi, I tried to download the suggested plugin, but nothing has changed. The theme arranges the categories in no particular order.
As you can see in the photo, there are two posts which, however, have a different arrangement of the categories, although they are all under the same sub-category (Italy -> Lombardy) one arranges the categories correctly Italy -> Lombardy -> monza and brianza while the other mix the order in Brescia-> Italy-> Lombardy (the correct one would be Italy -> Lombardy -> Brescia)
