I've installed the latest version of magento community edition via composer and all is working fine until i want to install an extension. I get the following:
PHP Version Check Your PHP version is . The required PHP version is . Show detail
PHP Settings Check * PHP Extensions Check missing PHP extensions. Hide detail
The best way to resolve this is to install the correct missing extensions. The >exact fix depends on our server, your host, and other system variables. Our PHP extension help can get you started.
I have gone over the server settings and have checked there is no variation on php versions which is currently on 7.0.17 all sites under this server are running the same. I've exhausted all options which i've found online such as modifying composer.json and there's no need for always_populate_raw_post_data=-1 as it's removed in PHP7.
