Erro ao ativar plugin

Ativando o plugin ocorre o seguinte erro. Não consegui identificar se é em meu servidor ou o plugin?

Warning: include_once(/var/www/html/wordpress/wp-content/plugins/wp-curriculo-vitae/admin/include/class.wpwls.php): failed to open stream: No such file or directory in /var/www/html/wordpress/wp-content/plugins/wp-curriculo-vitae/index.php on line 20 Warning: include_once(): Failed opening ‘/var/www/html/wordpress/wp-content/plugins/wp-curriculo-vitae/admin/include/class.wpwls.php’ for inclusion (include_path=’.:/usr/share/pear:/usr/share/php’) in /var/www/html/wordpress/wp-content/plugins/wp-curriculo-vitae/index.php on line 20 Fatal error: Class ‘WpWls’ not found in /var/www/html/wordpress/wp-content/plugins/wp-curriculo-vitae/index.php on line 21
