Hmmm, that’s a core error that is being displayed… I wonder if I can improve it by adding the path to the message. I’ll look into that after I finish this reply.
The directory is
../wp-content/uploads/ folder should be writable in a WP install and for some reason yours is not. You need to manually create the
csv_files and make sure it’s writable so the file can be uploaded into the folder.
I hope that helps!
