Why does not want to process index?

Question

PHP

Good day. I reinstalled the system, installed ubuntu, set up (as it seemed to me) the environment, installed all my php applications and suddenly got an error when accessing http://.../index/... 404, the file was not found, despite the fact that .htaccess did not change and before that everything worked, however, when accessing, say, http://.../admin/... everything works fine
In the error.log, this is

[Wed Apr 15 19:21:43.087917 2015] [negotiation:error] [pid 12545] [client 127.0.0.1:41437] AH00687: Negotiation: discovered file(s) matching request: /var/www/panel/index (None could be negotiated).
