In my case, issue was occured even after all these configurations have done (@Pekka has mentioned changes in httpd.conf & .htaccess files). It was resolved only after I add
<Directory "project/path">
Order allow,deny
Allow from all
AllowOverride All
</Directory>
to virtual host configuration in vhost file
Edit on 29/09/2017 (For Apache 2.4 <) Refer this answer
<VirtualHost dropbox.local:80>
DocumentRoot "E:/Documenten/Dropbox/Dropbox/dummy-htdocs"
ServerName dropbox.local
ErrorLog "logs/dropbox.local-error.log"
CustomLog "logs/dropbox.local-access.log" combined
<Directory "E:/Documenten/Dropbox/Dropbox/dummy-htdocs">
# AllowOverride All # Deprecated
# Order Allow,Deny # Deprecated
# Allow from all # Deprecated
# --New way of doing it
Require all granted
</Directory>
