I upgraded from WP 2.0.x to 2.1 this night. I followed the instruction in the manual.
After upgrad, the visual editor isn't working. It's loke like that . Only the pure HTML editor is working.
I tried to upload again the WP files (could be a file problem) but the result was the same.
Someone know what is happening? I tried to find a option to turn on the visual editor but I could not find it.
I can't do news posts in my blog since that.
