i was about to post it somehow at my prev reply, but i lost it.
anyway, it was very simple, and i made it again in 2 minutes.
what i did is
1. unzip the provided demos archive
2. share the demos folder in HFS
3. create the upload folder (i shared an /upload folder, in the root, permissions anyone)
4. open simpledemo/index.php
5. change this line accordingly
upload_url: "/upload",
6. remove this line
post_params: {"PHPSESSID" : "<?php echo session_id(); ?>"},
7. save as index.html
8. open /simpledemo/index.html in the browser, and upload your files. it works to me.
