I use for a while this tool. Always for the same purpose. Since yesterday it does not work anymore. I didn't change anything.

I get an error when I try to upload my csv file:

• The specified file temporary://20180817_0.csv could not be moved, because the destination is invalid. More information is available in the system log.
• Error moving file

What dit I do wrong? Where can I see the system log?

In attachement you see my csv file I want to convert.

thanks
