I have the strange problem. I installed Magento 2 on C9. I installed PHP 7, with all necessary extensions (curl, mbstring, mcrypt and etc). I set the php memory_limit 4096M. Checked by phpinfo you can see screenshot. https://nimbus.everhelper.me/client/notes/share/905628/sxvelb6o5xrt3q0tilem
But when I try to enable any extension I receive this error.
Your current PHP memory limit is 64M. Magento 2 requires it to be set to 756M or more.
Magento ver. 2.1.6
PHP Ver. 7.0.18-1+deb.sury.org~trusty+1
Could someone help me please?
