 * I just moved from mu-plugin to version hosted on wpackagist and I get this error
   now:
 * `PHP Fatal error: require_once(): Failed opening required '/sites/site.com/files/
   web/app/mu-plugins/../../../vendor/lkwdwrd/wp-muplugin-loader/src/lkwdwrd/mu-
   loader.php' (include_path='.:/usr/share/php') in /sites/site.com/files/web/app/
   mu-plugins/mu-require.php on line 2`
 * Looks like you have some paths hardcoded or missing composer package.
 * FYI this is a Bedrock stack.

 * Whoops, I just cleared out some mu-plugins and it started working, probably they
   haven’t get cleared properly.
