I used to be able to select which category in Query Post and Post Taxonomies & terms. I can no longer get the menu to select the category. I thought that this was because I wasn't using Pro. I bought Pro. I still can't use the feature. I can't even figure out how to activate Pro using WordPress. So perhaps I need to activate it and then I can select the category like I used to be able to. Any help would be greatly appreciated. I have tried on both Chrome and Firefox.
