XF 1.4 User/mod bar full width


I recently broke someone on my site styling and had to reinstall the theme. Before that I managed to make it so the user/mod bar was placed at the top of the page and was full width. In fact, a friend did this. I have asked him but he has forgot how he did it.

I have tried the UIX Page Style to 1 but that also messes with the navigation bar.

How can I do this? I need to fix this urgently!
