[dev_Incosys]

hello guys , 

i'm a beginner in magento , and tried installing an extension from magento market , but during the readiness check , i got this error , i tried some solutions i found in forums , but they didn't work , i increased memory in php.ini but in vain , could you suggest something that worked for you ? thank you 

ps : i fixed the cron scripts error by commenting 2 lines and replacing them in environment.php

Hi @dev_Incosys 

Did you check the Php and Magento version supported by the extension? You are on which version of Magento? 
You recently installed Magento or your site was already running on Magento before you tried installing extension.
