Add text/csv to list of MIME types
For some reason this common file format is missing in the default installation which means that .csv files can get some strange MIME type that is decided by the browser uploading the file (eg. application/vnd.ms-excel). Or no MIME type at all when using the FTP upload.
In case this is urgent for someone a server admin can easily add it manually:
MIME type: text/csv File extension: csv
