I've just upgraded to version 3.0 I'm trying to upload an image so I can have a custom header.
The next thing that happens after I press upload I see a new window where its blank and says crop and publish, then it loads a rectangle the size of my photo and later the rectangle you can resize to crop the image. I don't know a way to "accept" the crop other than clicking outside the crop rectangle, then it desappears and leaves the crop and publish button. I press it and in the preview window there is just a blank rectangle where my image is supposed to be.
If I load my blog I also see just a blank rectangle.
I've tried reinstalling version 3.0 a couple of times automatically (from the dashboard) and once manually. So far nothing changed.
there is also another problem, when I go to install a new theme I can't preview it I just get a blank square, don't know if this is related.
