I have just done a clean install and my media uploader thickbox shows the broswer not the media uploader.
This happens using twenty ten as well as the theme i was planning to use.
As mentioned i did a totally clean install on a new cpanel database as before the uploader worked on twentyten and not on the theme i had chosen.
When i did the clean install it didnt work on twenten either.
Am using 777 for all permissions as well.
Any ideas gratefully received.
Will using an older version of wordpress help?
