I am trying to install Magento 2.1.5 and I'm currently stuck on the readiness check. It is currently giving this error

> PHP Settings Check * Need Help? PHP Documentation Your PHP Version is

I have renamed the php.ini file and have included the stipulated line and still have no luck. My ini file is as follows:


    ; Copyright © 2013-2017 Magento, Inc. All rights reserved.
    ; See COPYING.txt for license details.
    ; This file is for CGI/FastCGI installations.
    ; Try copying it to php5.ini, if it doesn't work

    memory_limit = 1024M
    max_execution_time = 18000

    ; disable automatic session start
    ; before autoload was initialized

    flag session.auto_start = off
    always_populate_raw_post_data = -1
    ; enable resulting html compression

    zlib.output_compression = on

    ; disable user agent verification to not break multiple image upload

    suhosin.session.cryptua = off

    ; PHP for some reason ignores this setting in system php.ini
    ; and disables mcrypt if this line is missing in local php.ini

    extension=mcrypt.so

    ; Disable PHP errors, notices and warnings output in production mode to prevent exposing sensitive information.
