Hi,
I am getting the same error while trying to upload an image from the File field created through Simple Fields. It works fine when I try to upload an image file from the default wordpress post options.
When I saw the links, I found that Simplefield does not populates the post id while trying to upload a file.
Link through Simplefield:
http://localhost/wordpress/wp-admin/media-upload.php?simple_fields_dummy=1&simple_fields_action=select_file&simple_fields_file_field_unique_id=simple_fields_fieldgroups_1_3_1&post_id=-1&TB_iframe=true&width=640&height=448
Link through default wordpress post:
http://localhost/wordpress/wp-admin/media-upload.php?type=image&post_id=4&simple_fields_action=select_file_for_tiny&TB_iframe=true
If you carefully notice, the post id comes up as “-1” instead of “4”. When I had updated the link manually using firebug and tried uploading the file, it worked. Hence it is clear that the issue is with the population of post id while trying to upload a file through Simplefield.
Can anyone please help me sort out this issue.
