Same problem fixed in an easier way. It’s seems that an option in an update puts the text editor by default.
Just go in “user”, select your profile, than “modify” and uncheck the option that put the text editor by default (don’t know the english name but it’s the first one at the top of the page… It must be “Disable the visual editor to write” or something)…
