By the phpspreadsheet plugin I’ve created an excelfile which logs form queries.
When I first download this file via the panel,
then it shows weird chars like this in LibreOffice:
When just download it again, then the excelfile is displayed correctly.
I first thought that that file has not been downloaded completely.
But it does not matter how long I wait. The file is very small anyway.
Any idea what is going wrong?
