Problem:
Client is using the Forms cred_form_ajax_upload_validate hook to restrict the acceptable file types that can be uploaded for a file custom field, but it is not working, the accepted file types are being rejected.

Solution:
Their code wrongly defines the file types which do not match the file type reported by the global $_FILES object used for the test (e.g. they are testing for "application/text" instead of "text/plain".
