AH01630: client abandoned Apache server configuration

I am getting this error when trying to access localhost through a browser.

403 Forbidden

I am using Ubuntu 14.04 LTS

Here is my config file:

etc. / apache 2.conf

    # This is the main Apache server configuration file. It contains the
    # configuration directives that give the server its instructions.
    # See http://httpd.apache.org/docs/2.4/ for detailed information about
    # the directives and /usr/share/doc/apache2/README.Debian about Debian specific
    # hints.
    #
    #
    # Summary of how the Apache 2 configuration works in Debian:
    # The Apache 2 web server configuration in Debian is quite different to
    # upstream suggested way to configure the web server. This is because Debian'sA
    # default Apache2 installation attempts to make adding and removing modules,
    # virtual hosts, and extra configuration directives as flexible as possible, in
    # order to make automating the changes and administering the server as easy as
    # possible.

    # It is split into several files forming the configuration hierarchy outlined
    # below, all located in the / etc / apache2 / directory:
    #
    # / etc / apache2 /
    # | - apache2.conf
    # | `- ports.conf
    # | - mods-enabled
    # | | - * .load
    # | `- * .conf
    # | - conf-enabled
    # | `- * .conf
    # `- sites-enabled
    # `- * .conf
    #
    #
    # * apache2.conf is the main configuration file (this file). It puts the pieces
    # together by including all remaining configuration files when starting up the
    # web server.
    #
    # * ports.conf is always included from the main configuration file. It is
    # supposed to determine listening ports for incoming connections which can be
    # customized anytime.
    #
    # * Configuration files in the mods-enabled /, conf-enabled / and sites-enabled /
    # directories contain particular configuration snippets which manage modules,
    # global configuration fragments, or virtual host configurations,
    # respectively.
    #
    # They are activated by symlinking available configuration files from their
    # respective * -available / counterparts. These should be managed by using our
    # helpers a2enmod / a2dismod, a2ensite / a2dissite and a2enconf / a2disconf. See
    # their respective man pages for detailed information.
    #
    # * The binary is called apache2. Due to the use of environment variables, in
    # the default configuration, apache2 needs to be started / stopped with
    # /etc/init.d/apache2 or apache2ctl. Calling / usr / bin / apache2 directly will not
    # work with the default configuration.


    # Global configuration
    #

    #
    # ServerRoot: The top of the directory tree under which the server's
    # configuration, error, and log files are kept.
    #
    # NOTE! If you intend to place this on an NFS (or otherwise network)
    # mounted filesystem then please read the Mutex documentation (available
    # at);
    # you will save yourself a lot of trouble.
    #
    # Do NOT add a slash at the end of the directory path.

    # identification number when it starts.
    # This needs to be set in / etc / apache2 / envvars
    #
    PidFile $ {APACHE_PID_FILE}

    #
    # Timeout: The number of seconds before receives and sends time out.
    #
    Timeout 300

    #
    # KeepAlive: Whether or not to allow persistent connections (more than
    # one request per connection). Set to "Off" to deactivate.
    #
    KeepAlive On

    #
    # MaxKeepAliveRequests: The maximum number of requests to allow
    # during a persistent connection. Set to 0 to allow an unlimited amount.
    # We recommend you leave this number high, for maximum performance.
    #
    MaxKeepAliveRequests 100

    # The default is off because it'd be overall better for the net if people
    # had to knowingly turn this feature on, since enabling it means that
    # each client request will result in AT LEAST one lookup request to the
    # nameserver.
    #
    HostnameLookups Off

    # ErrorLog: The location of the error log file.
    # If you do not specify an ErrorLog directive within a 
    # container, error messages relating to that virtual host will be

    # your system is serving content from a sub-directory in / srv you must allow
    # access here, or in any related virtual host.

I added to apache and I updated the service and always repeat the same error. I would like to know why this is not working. Perhaps I would like to chmod this site locally on any type of media. Please your help and good evening
