Here's my /private/etc/apache2/httpd.conf file:

...
LoadModule rewrite_module libexec/apache2/mod_rewrite.so
LoadModule php7_module libexec/apache2/libphp7.so
LoadModule perl_module libexec/apache2/mod_perl.so
...
User _www
Group _www
...
DocumentRoot "/Users/myuser/Sites"
<Directory "/Users/myuser/Sites">
    Options Indexes FollowSymLinks Includes ExecCGI
            AllowOverride All
            Require all granted 
</Directory>

But when I go to http://localhost it returns '403 forbidden'.

Couldn understand anything. I gave chown to that folder etc. But nothing solved that.
