You didn't listen to me. I said to use the 2nd way. Your 2nd screenshot is the correct way to include members and guests. (it also says it in the documentation)
This one.
The other way won't work because it asks a user to be a guest AND logged in at the same time. And this is not possible.
This one.
Also, your question is actually not related to this addon but is a core XF thing. So it is "intended" by design by XF, not by this addon.
User criteria is a XF core feature. And people usually have problems with it because it is not very clear how it works.
To explain it to you, the criteria system is based on "AND" principle (with exception). So whatever you pick as a criteria, if you pick more than one criteria, then it becomes an "AND" clause. So criteria x AND y must be met to work.
But a visitor can't be at the same time logged in AND be a guest. It can be one or the other. A member can't be a guest, as it is logged in. A guest can't be logged in. But in your criteria you ask the person to meet both criterias, which doesn't work.
The exception is that you have to use the 2nd way described. As you can see in the description it says "
any of the selected usergroups". That one alone works based on "OR" principle. So it is enough for a user to meet one of the criterias. So picking "registered" and "unregistered" covers all cases.
This is a bit confusing because in all the other areas the criteria system is based on AND, but inside this one criteria it is based on OR.
