What might cause a POST to wp-admin/async-upload.php to return JSON >and< HTML?

I had the same issue and did not find any information in my debug output. It worked out, that DOING_AJAX was not defined (I don’t know why). Changing the beginning of async-upload.php from if ( isset( $_REQUEST[‘action’] ) && ‘upload-attachment’ === $_REQUEST[‘action’] ) { define( ‘DOING_AJAX’, true ); } to define( ‘DOING_AJAX’, true ); worked … Read more
