In Magento 2.1.0 I do the Readiness Check when installing new extensions. The readiness check tells me that my memory_limit is set to 800M, but the server is set to 2000M and I have changed the .htaccess file in shop root so it it set to 2000M two places in that file as well.
Where else can it be set?
in .htaccess Two memory_limit will be available
Please change it in mod_php7 and try seeing phpinfo() on your browser.
If it is still displayed as 800M Then your are editing in a wrong file. Change it in your last loaded ini file.
