Problem solved.
I live in Norway and my default CSV is using ; instead of , .
I changed ; to , and then the import went fine.
Thanks.
I tweaked the code so i managed to remove it,.
However, the date issue is because of the code- for somehow reason it shows the “Modification” date of the post instead of Publish date. I tweaked this also so i got is exactly as i wanted. But would be great with a functionallity instead.
