Firstly, I apologise if this is in the wrong area.
So, I'm trying to change the layout of my blog. I downloaded a bunch of themes and I'm trying them out to see how they might look. I found one called origami that I like, when I 'live preview' the theme, there is an option at the end of the customisation panel that says (it's in a green box) "get additional customizations" I'm reaaallly curious to see what these additional options are, however, every time I click it I just get a blank page that says:
"You do not have sufficient permissions to access this page"
I have no idea why it's doing that =/ I know it's probably really obvious, I'm pretty terrible at the whole coding thing. Thanks in advance for any help/advice! :)
