wp_handle_upload error on Post Write – “Specified file failed upload test”

Hi,

This is a problem I’ve been having when trying to code in a custom uploader into the Post Write page in the backend.

The wp_handle_upload keep returning with “Specified file failed upload test.” even thought the file gets uploaded. I’ve gotten this working on my own custom wordpress page.

Thanks.
