When I tried to install new modules it shows a error that says
"Your current PHP memory limit is 256M. Magento 2 requires it to be set to 756M or more. As a user with root privileges, edit your php.ini file to increase memory_limit. (The command php --ini tells you where it is located.) After that, restart your web server and try again."
I edited php.ini file but it didn't work. It also contains a php.ini.sample file in root. I have a shared hosting plan and hosting provider says they won't increase php limit size from their side in case of Shared hosting plan. Someone please help me. What should I do?
