CSV Metadata can't be uploaded


I have a problem uploading my CSV with metadata for my STOCK FOOTAGE. I’ve uploaded more than 5 during the previous week, and now, for the same file (.csv), it says:

File metadata.csv is not an accepted file type. The accepted file types are text/csv,.csv


I’ve also tried to name it “csv.csv” and everything else…

Hope sbdy can help me.

Best Regards,
