For me the following worked which is copied from example in /etc/apache2/apache2.conf
:
<Directory /srv/www/default>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
Require all granted
option is the solution for the first problem example in wiki.apache.org page dedicated for this issue for Apache version 2.4+.
More details about Require option can be found on official apache page for mod_authz module and on this page too. Namely:
Require all granted -> Access is allowed unconditionally.
