 * Recieving this error when trying to activate plugin via plugins page. Tried installing
   manually and via WP admin with the same results..
 *     ```
       Plugin could not be activated because it triggered a fatal error.
   
       Warning: require_once(__DIR__/composer/autoload_real.php) [function.require-once]: failed to open stream: No such file or directory in /home1/shanessp/public_html/dev/hcaa/wp-content/plugins/newsletter-sms-smsapi/vendor/autoload.php on line 5
