Great to all who found the answer... me still looking :(
I have done ALL and above, and i am done to this situation:
did a local COMPLETE FRESH install, so downloaded the latest version 3.4.2
Created an EMPTY db,
opened the 'new-post' screen... and??? no VISUAL editor
So, a complete fresh install, and STILL nothing? pfff...
i then started to downgrade,
3.2.1 BINGO! "suddenly" the visual editor is back again. Happy, but actually not.
Upgrading again got 3.3.0 and again nothing...
So, now i am really in a weird situation. I need to start using the old version?
What is the difference?
And again, this is a clean install. no plugins installed, no themes etc...
