Why do I get "Autodetect: no header row found for file xxx"

[Anonymous]

I'm trying to import a list of about 3k leads.
I've done everything as always but I get this message after the import step 1 (select file):

"autodetect: no header row found for file '/usr/local/marketo/tmp/php84LjRG'"
I've checked and there IS a header and the file is CSV as always. Not sure why it's saying that?
Any ideas?

Thanks!

A few things I always do when I encounter this error.

• Make sure that every column has a heading in the first row.
• If the file type is set to  "Autodetect", change to CSV.
• Insert a blank row at the top of the file, save the file, then delete the row and save it.
• Delete several columns after the last column of data.
