A strange error has suddenly appeared on my copy of wordpress. I updated to the latest version the other day, so it might be something to do with that.
Here's an image of what I see when I go to create a new post:
It is permanently stuck on the HTML view (even though the selected tab is 'visual') and won't let me select the visual mode. Further, in HTML mode all the text is white, making it impossible to type anything against the existing form's white background!
I'm very confused! Anyone have any ideas how I can fix this? I've disabled all plugins and this hasn't fixed anything.
