Topic: error when activating xstore theme

When I attempt to activate the theme, it produces this error:

Warning: require_once(__DIR__/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in /home/covocup/public_html/wp-content/themes/xstore/framework/thirdparty/vendor/autoload.php on line 5

Fatal error: require_once() [function.require]: Failed opening required ‘__DIR__/composer/autoload_real.php’ (include_path=’.:/opt/php52/lib/php’) in /home/covocup/public_html/wp-content/themes/xstore/framework/thirdparty/vendor/autoload.php on line 5

I followed that path in cpanel and fount autoload.php. This is the content of that file:

<?php

// autoload.php @generated by Composer

require_once __DIR__ . ‘/composer’ . ‘/autoload_real.php’;

return ComposerAutoloaderInitc19d6f3cbd0b8e6690af9ad0a69c9ca5::getLoader();

I thought the problem might be with activating the included plugins, so I downloaded them from http://www.8theme.com/download-plugins/ and uploaded the to the site.

When I attempt to activate Xstore core I get a white screen. I figure that is because the theme will not activate. And when I attempt to activte WPBakery Visual Composer I get:

Fatal error: Cannot redeclare class Vc_Manager in /home/covocup/public_html/wp-content/plugins/js_composer/js_composer.php on line 33

So some help getting these activated would be greatly appreciated.
