UNEXPECTED_ ERROR August 01, 2019, 08:41:17 AM I had this challenge today while uploading a pairwise job. Under VIEW RESULTS, the pop-up icon was:ERROR, and under progress: FILEPREP WAS NOT SUCCESSFUL and it was at 1%. After clicking on the Error bar, i got: Unexpected _error and under DESCRIPTION:oops ... an unexpected error occured. Please notify the developers at firstname.lastname@example.org (which i`ve done). I will greatly appreciate anyone who can help resolve this challenge. Many thanks.
