Cannot create/edit posts in WordPress 4.3

[fabcorrea]

Hi there. I am having a big issue related to my dashboard. Since I updated it to wordpress 4.3 I cannot create/edit/update any of my stuff. For instance, I cannot create/edit/update pages, posts or categories. Everytime I click the update button, the loading icon stays busy and the page never updates it. Please help me out!

Hi @fabcorrea, welcome to Trac.

Does it still happen with all plugins disabled and a default theme (Twenty Fifteen or Twenty Fourteen) activated?

I'm afraid the problem is related to the theme and some plugins as well. I disabled all plugins and activated the default theme and the problem was gone. Then I just activated the theme back, and the problem came back again. Then I activated the default theme once again, so no problems.... but then I activated the plugins only (with default theme) and the problem came back once again. There is a way to return to previous version of wordpress?
