When uploading media, I can't get the Flash uploader to show up. It only shows the "Browser uploader" with no option for Flash uploader. But when uploading with the same computer on a different WordPress blog (hosted elsewhere) it does show up.
• I am up-to-date on my Flash player.
• I've gone in through FTP and the flash files needed in the "wp-includes/js/swfupload" are there.
Interestingly, when I use this URL,
"http://myblog.com/wp-admin/media-upload.php?post_id=1&flash=1"
the Flash loader shows up and starts uploading some files but not others, saying "HTTP error." Even the ones that do "upload" don't show in my Media Library.
Any ideas? Is this because of my hosting? If so, what do I need to ask of my webhost?
