Import CSV not working

Hi guys,

I have been trying to upload a new csv with listings and I keep getting an error.
I have already tried a few things like copy and past info into new file and start from scratch but the error keeps coming up. I have also tried to upload a file which I uploaded successfully in the past and that does not work either.

I am obviously trying to upload a csv but the following error comes up in the field to the left of the Select and Upload button (see attachment).

Array( [error] => Sorry, this file type is not permitted for security reasons.)x

I noticed that you changed the sequence of columns for the upload so downloaded a new sample csv and all in line with the new sample file now.
Please find the csv attached also.

Any ideas?

Thanks!!
