I'm having an issue with my Magento 2 , was working fine at the beggining , I've installed a few modules, and now, when I try to enable a module from Admin - System - Web Setup Wizard, I get this error:
PHP Version Check
Your PHP version is . The required PHP version is . Show detail
My php version is 5.6 so it should be good, also I have my cron jobs set up. It seems like there is an issue with the core of Magento and/or a specific module that I've installed, which affects the readiness check and due to that reason it fails.
