Apache 2.4.6: client denied by server configuration (PHP FPM) - apache

Question

I found a similar question but it did not helped.
When I open a PHP file via https://site/test.php, the following error comes:
[Tue Oct 29 11:15:53.480855 2013] [authz_core:error] [pid 5424] [client xxx.xxx.xxx.xxx:xxxxx] AH01630: client denied by server configuration: /vhost_site_ssl

I suppose this error is caused by upgrading apache 2.2 to 2.4. I also read this: http://httpd.apache.org/docs/2.4/upgrading.html but did not helped.
UPDATE
I forgot to attach te exact error page:
Forbidden
