Hello guys. I have a question.
Why is the navigation menu different on iPhone? And how do i eventually fix it, if there is an option for it?

(this is how it looks on pc, and thats how I want it to look like on mobile devices)

(thats how it looks like on my phone)
As you can see, on my iPhone it is 2 homes, forum and members. But I would like to change it so it have the same tabs as on computers. Is it possible, and how?
