Yeah. A while ago, I discovered I could only edit from MonoBook. In the modern view, the editor never loads. But here in the MonoBook, that contribute button doesn't appear. So I have to log out to view the modern version, click the dropdown, select New Page, and then when the editor opens, I have to log in again to edit via MonoBook. It's a little tedious, admittedly.
But the more important question is why can't you edit using the default skin? Many of our features only work on Wikia skin, and our help pages are designed for those using the default.
If those don't seem to be the problem, you could always contact us and one of the more techy types will try and help
