I upgrated to the latest version of Worpress a couple of nights ago and began working on a post last night by just uploading a picture and sending it to the visual editor as I always do. It all worked fine and the picture appeared fine, so I save that and got back to it today, but somehow it is only showing me the HTML code on the backend and doesn't let me send pictures to the visual text box.
I also cannot switch between Visual and Code, although both tabs are present.
I usually use Firefox but thought I'd try with IE6, but I have the same problem, and the backend actually looks all out of place. I also tried on Firefox on my Mac, but had the same problem again.
I cannot view older posts in visual mode either. It all looked fine after the upload, and now it is not working and causing me a big problem. Can anyone help?
