Phabricator GUI is not showning... facing some script and/or server issue - phabricator

Question

I am trying to do some hands on with phabricator. Few days before I tried to set it up using the official setup link:
Official installation link
But following this link I was getting 'path' not set problem and even following solutions available online, I couldn't resolve that issue.
So tried another link.
A day before yesterday I was able to use every available feature in from phabricator's UI but after a restart I am stuck with its UI and getting below given text while trying to access the server:
setException($ex);PhabricatorStartup::endOutputCapture();$sink->writeResponse($response); } catch (Exception $response_exception) { // If we hit a rendering exception, ignore it and throw the original // exception. It is generally more interesting and more likely to be // the root cause. throw $ex; } } } catch (Exception $ex) { PhabricatorStartup::didEncounterFatalException('Core Exception', $ex, false); } function phabricator_startup() { // Load the PhabricatorStartup class itself. $t_startup = microtime(true); $root = dirname(dirname(__FILE__)); require_once $root.'/support/PhabricatorStartup.php'; // If the preamble script exists, load it. $t_preamble = microtime(true); $preamble_path = $root.'/support/preamble.php'; if (file_exists($preamble_path)) { require_once $preamble_path; } $t_hook = microtime(true); PhabricatorStartup::didStartup($t_startup); PhabricatorStartup::recordStartupPhase('startup.init', $t_startup); PhabricatorStartup::recordStartupPhase('preamble', $t_preamble); PhabricatorStartup::recordStartupPhase('hook', $t_hook); }
This is the content of file:
&ltVirtualHost *:80&gt
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.
#ServerName www.example.com
ServerAdmin myhost.co.in
DocumentRoot /var/www/phabricator/webroot
# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
# error, crit, alert, emerg.
# It is also possible to configure the loglevel for particular
# modules, e.g.
#LogLevel info ssl:warn
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf

Install PHP. This is required.
