Replacing the codeigniter 2.1.0 system/libraries/upload.php with 2.1.2 version upload.php library solves the problem. Hope this helps

Answer 6

Actually, in my case, I created a blob object from a canvas by void canvas.toBlob(callback, mimeType, qualityArgument) method So the blob file does NOT have its real name (which has an extension), it's just only 'blob'. So I have to use the legacy way to upload the file, instead of an 'upload' library:

move_uploaded_file ( $file["tmp_name"], $target_file )
