I['m getting a similar problem I think. When I attempt to save I get the error message "a script on this page may be busy or may have stopped responding". If I choose to continue, after a short time the entire content of the wiki seems to disappear. I tried using the clean HTML button, but this didn't help any. I'm a newbie to moodle, so please guide me accordingly. I want to use the wiki, but it's not much use if everything deletes when I try to add something.
