I have that and have added three buttons. i’m either blind or that is no longer an option.
This section allows you to add up to 4 buttons – a create topic button, a subscribe button and a profile button, and if activated a button for unread topics. You can then style and display them in any order
This is on the buttons tab. The unread is not an option and no instructions on how to activate it.
I think it’s broken. I checked and unchecked every possibility I could think of in the unread posts tab. The button never shows up in the buttons tab and none of the unread features show in the Forums.
