I download absolutely new, the last version of MAMP 3.5.
I go to phpInfo and it says the PHP version is 7.0.0 and Configuration File (php.ini) Path is: /Applications/MAMP/bin/php/php7.0.0/conf.
I go to php.ini in that path and change errors to on: display_errors = On. I check that: error_reporting  =  E_ALL.
I Stop Servers and Start Servers. I reload the page in the browser. I check phpInfo and now display_errors is on.
I do not see the errors.
I have checked all the solutions in the web, just to name a few: 
MAMP Config help, display PHP errors
Why MAMP doesn't display errors?
how to display errors on MAMP?
I tried everything and I do not see PHP errors. What else can I do?
