When trying to upload images using WordPress 3.0 the media window is blank (except for the header 'Upload new media'. As such I don't even have the option to select 'Browser upload' as that along with all other input fields is missing. This was working just fine when using version 2.9. Have reinstalled WordPress 3.0, recreated database but still the problem persists. Default theme and my custom theme all have the same issue. I am using a Mac and have tried three types of browser all to no avail. Strangely however if I login on a Windows machine it all works fine, so I assume this is some bug with Mac and WordPress 3.0? Please help. It's driving me nuts and my theme is only WordPress 3 compatible.
