Both WordPress 4.5 RC1 and RC2 have this problem, I don’t test other WP version.
I have installed on our demo and it still work fine, you can send me username & password of your site for further checking.
Also, you can try deactivate all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one and let us know if you find the problematic plugin(s). Maybe there is a conflict in plugins.
