All of a sudden, my blog's visual editor is not showing anymore. I can only make posts and edit them in the CODE editor, currently. Also, some special characters in the blog posts are not showing correctly anymore. They're now some sort of strange #ä"§($ etc.
I really don't know how to fix this, as I've already installed the new WP version (the problem had started while using WP 2.1.3) and it still doesn't work. It's work in all of my blogs but this one, and I haven't changed or broken anything as far as I can tell.
This is my main blog, so I'm really dependent on your help and it will be highly appreciated!
Looking forward to your replies. Thank you so much!
