Hopefully this helps others who may run into this problem. I see there was a post about this a year ago with no response.
When attempting to upload multiple files using the flash uploader (ie. plupload), after the first file every subsequent file would return the error and fail.
“Invalid upload. Error Code : 3”
Without going into the nitty-gritty details, essentially the browser is using the same connection (keepalives) for subsequent uploads which causes the files to be rejected (UPLOAD_ERR_PARTIAL).
Implicitly send the ‘Connection: close’ header. Tells the browser not to reuse the connection for the next request (in this case, upload).
header('Connection: close');to nextgen-gallery/admin/upload.php.
