Start by reproducing the upload using the attached contoh_upload_jurnalumum_edit.xls file on PHP 5.3.8 with Ubuntu Server 12.04, XAMPP, and CodeIgniter 2.1.3. Compare the browser connection reset with the expected array result, and consider the issue resolved when the file uploads and returns the array without a reset in the reported environment.
