Discussed with Sir Reon the error encountered in the application when generated a file, there are no data in the file, as per sir Reon, the server got corrupted thus they fixed it and restored all the backups, but when generated a file using mall sending, it is when the error is encountered, discussed that the error is not encountered only now, discussed that I will need to check the data first before proceeding to check the application, as per sir Reon, he will dump the database in sftp for me to get and to check.
