Hi Jan,
Grateful for your prompt answer thanks to which my problem is solved : it was one of the plugins : WP-POLLS.
I do not understand though why this could occur since I never used this plugin, instead I use Lasonde.fr. Especially during the night, since everything was ok yesterday but not today !!!
So the visual editor works again and I am adding TinyMCE functions which I installed this morning.
On the other hand, please do tell me why my editor looks dated, as I know I have WP 3.4.2.
Thanks again & cheers.
