Import only the first row

I have this csv exported from google spreadsheet: https://www.pastefile.com/BuhQkt

Unfortunally the plugin import only the first row and then it hangs up: https://pasteboard.co/HRdseYq.png

I’ve tried:
> check that the cron is active: OK.
> check that the file is encoded in UTF-8 (without BOM): OK.
> change the order of the rows: did, same result.
> use a simple csv with only “x” on every column: did, same result.
> use a file generated by libreoffice excel: did, same result.

The only problem I’ve noticed is under the minimum requirements. I had:
– max_execution_time: 900 (minimum requirement: 3000)
– max_input_time: 60 (minimum requirement: 3000)
– max_input_vars: 1000 (minimum requirement: 3000)

So I’ve tryed to change these settings with this code in functions.php:
ini_set( ‘max_execution_time’, ‘3000’ );
ini_set( ‘max_input_time’, ‘3000’ );
ini_set( ‘max_input_vars’, ‘3000’ );

Unfortunally only the max_execution_time seems to be changed. Now I have:
– max_execution_time: 3000
– max_input_time: 60
– max_input_vars: 1000

With this values, I tried again, but I got the same result: only the first row is imported and then the plugin stucks.
