 * I get this error i nothing about why all i know how to do is put plugins in the
   director and activate them.
 * I put this in here for feedback. It’s the only time it’s happened to me for any
   plugin i’ve activated!
 * Warning: require_once(/home/invest/public_html/blog/wp-admin/install-helper.php)[
   function.require-once]: failed to open stream: No such file or directory in /
   home/invest/public_html/blog/wp-content/plugins/subscribe2/subscribe2.php on 
   line 217
 * Fatal error: require_once() [function.require]: Failed opening required ‘/home/
   invest/public_html/blog/wp-admin/install-helper.php’ (include_path=’.:/usr/lib/
   php:/usr/local/lib/php’) in /home/invest/public_html/blog/wp-content/plugins/

 * [@jaffasoft](https://wordpress.org/support/users/jaffasoft/),
 * I think this has been answered over on the plugin website but for completeness:
 * The install-helper.php file (part of the WordPress core) is apparently missing
   on your server. You need to restore this file and it will work.
