Well this sucks.
The View, Edit, Customize/Edit Theme, and Home/Dashboard buttons are all gone when I go to my different blog posts.
I noticed it a few days ago, but I thought it was simply a memory/cache thing not loading the pages fully.
But it’s there when I use the computers on campus and log in to my account, so what gives? 
It’s not my tumblr theme, then, clearly.
The only thing I can think of is that it might be an X-Kit setting I put in. But I’m too scared to disable X-Kit and lose all my customizations. :’(
Or it might be my computer, but what would that have to do with anything? It loads everything else just fine. Maybe it’s the size of my screen? But I zoomed in and out and don’t see the buttons in the corner anywhere. :
And it’s only happening on my MAIN blog; I just checked, and my side blogs are all showing the buttons just fine, wtf; and they all use the same theme. #officiallyconfused
Good news is I can still edit/delete my posts, either straight from the Dashboard, or by using the tumblr.com/edit/1234567890etc link, which is good at least. But I like buttons, man. Buttons are nice.

Looks like I’m missing mines as well. I just edited my theme from home, using the Customize option (top right). I hope to find a better fix
That was one of the first things I tried, yup. I googled the issue first, and everyone was like It’s Your Theme, so I checked it while I was on campus and the buttons shows just fine with the theme. I really think Tumblr hates my computer specifically. 😦 Only thing is: X-kit isn’t active on the campus computers, which is why I suspect that a setting is screwing me over. *scratches head*

I had this problem and it turned out to be adblock. I don’t know if you have it but if you do try disabling it.
I don’t have adblock. *scratches head vigorously*
Tumblr, y u so mean?
