Fatal error: require_once()

As soon as I activated this plugin, I am getting error whenever I visit my website.
I uninstalled all the plugins+themes, reset dashboard to initial settings, still I get this error when ever I visit my website from any other Mobile/PC:-

“Warning: require_once(/home/gkbullet/public_html/wp-content/plugins/sydney-toolbox/inc/post-type-services.php): failed to open stream: No such file or directory in /home/gkbullet/public_html/wp-content/plugins/sydney-toolbox/sydney-toolbox.php on line 60

Fatal error: require_once(): Failed opening required ‘/home/gkbullet/public_html/wp-content/plugins/sydney-toolbox/inc/post-type-services.php’ (include_path=’.:/usr/share/php’) in /home/gkbullet/public_html/wp-content/plugins/sydney-toolbox/sydney-toolbox.php on line 60”

Please help.
