Sorry to hear you are having trouble importing a CSV file! I would recommend verifying that your file follows the CSV file requirements. And, give the CSV Import Tips a thorough read. These two sections resolve nearly all issues with importing a file.
What are those array_map() and array_merge() errors? They could possibly help clue into the cause of the issue. It is possible if PHP is showing errors, it is the display of those errors which is causing the import to fail. It is considered a best practice to suppress or log those errors on a live site as they could leak sensitive server information publicly. Here’s a link to a tutorial which explains how to suppress those errors and warnings.
If you can attach your file, as a private reply, I’ll take a look at it asap so I might be able to offer a more specific solution.
