 * I get the following errors at least once a day :
    `E_WARNING: include(): Failed
   opening 'wp-content/plugins/wp-super-cache/wp-cache-base.php' for inclusion (
   include_path='.:/app/.heroku/php/lib/php')`
 * `E_WARNING: include(): Failed opening 'wp-content/plugins/wp-super-cache/ossdl-
   cdn.php' for inclusion (include_path='.:/app/.heroku/php/lib/php')`
 * looked anywhere but couldnt find a way to solve this.

 * Was the plugin installed correctly? Were those two files in the wp-content/plugins/
   wp-super-cache/ directory?

 * yes, I re-installed it. the files are in the directory.
    the calls are coming
   from /wp-admin/admin-ajax.php.
 * Thanks,

 * What is the value of WPCACHEHOME in wp-config.php ? Is it “wp-content/plugins/
   wp-super-cache/” or is the the full path to that directory from “/” ?
 * If it’s only the above, make sure it’s the full path.
