Admin panel not working after update

I was using it to publish on Tumbrl the excerpts of my posts.

EDIT: I previously had the “You are not allowed to edit this post.” on save draft issue! That’s why I first disabled it.

(Is it better on your website? For me it’s the same.)

Can’t really say: I maybe went in some advanced settings I shouldn’t have.
I didn’t add/remove any “export module”, so to speak.

The problem raised when I couldn’t post anymore and the editor had only a “Submit for review” instead of “Publish” button; also categories were resilient to any change.

I resolved this trying many fixes, including working on databases: that could have also added more confusion to the picture…

PS: I’m sorry, I take this is of little help to understand what happened, but I couldn’t figure it out myself.
