An appropriate representation of the requested resource /art/wp-admin/media-upload.php could not be found on this server.
I get this now EVERY time I try and put on an image from the media library OR from a link using the media library.
I had to turn off the Flash setting when it first all got upgraded, a couple of weeks ago now, and it worked fine. All of a sudden, with me not changing a thin on my WP, I have got this error start.
I have tried reuploading the whole site but it made no difference.
Now this is a major problem for most people, but as I run an art site this is an even bigger one for me. Please can someone help me get my images back!
