I am having a problem in selecting categories with this widget. In the "Categories" section, the only option it is giving me is "All". Therefore, I am not able to select the categories that I would like to display. Please see the attached screenshot.
If any coding is required to fix this, then please make it something that I can do with a "Code Snippet", as that is where I have put in all my other fixes.
I am running the Good Old Classipress 3 child theme over the latest version of Classipress 4.
