I've recently updated to WP 4.5 and it seams I cannot change passwords or add new users, because clicking "Show password" (when adding user) or "Generate password" (when editing user) does not work (no errors and no requests shown in the console/network dev tools tab in Chrome).
Also I noticed some other buttons not working, for ex. "Screen options" or "Help" dropdowns in the upper right coer.
I have also updated my theme to the newest version.
Please advise!
