This issue started intermittently several days ago but now seems permanent. I can't upload images of any size. They start uploading and the progress bar just freezes. Sometimes it doesn't even get started, sometimes it almost makes it to the end. Tried loading all different image sizes, even images I've uploaded before. no luck. I'm on WordPress 3.3.1 and the latest Flash (as of Feb 2012) but simple uploader doesn't work either. I can't add anything to my sites. Does anyone have any suggestions? I've cleared my browser cache twice, cleared cookies. Help!
