Last night I uploaded a single picture using the same method I have a thousand times before. But this time something broke. The image never appeared in the post and now I can't even edit it. Whatever changes I make to the post are lost when I click save, and I can't even click the HTML tab to see what happened to the code. I didn't install any plugins, I didn't edit the WP code, and I didn't change anything...it just stopped working once I uploaded that image and hasn't worked since.
