rich text editor vanished lots of JS errors

Thank you for your help

Anyway, all the JS warnings and errors are in this screenshot:

Podz: the Wysiwyg worked just fine. Maybe one of the plugins i’ve installed caused a conflict? Anyway, disabling the plugins didn’t help.
You mean, checking the current directories with the original WP installation folder?

The main JS errors are:
