# Missing PluginOrganizerMU.class.php

 * I installed the plugin then moved the file PluginOrganizerMU.class.php from the
   public_html/sitename/wp-content/plugins/plugin-organizer/lib folder to the
    public_html/
   sitename/wp-content/mu-plugins folder, as required.
 * Everything was going fine then suddenly I noticed some ‘strange’ behaviour and
   I discovered that the PluginOrganizerMU.class.php file has completely disappeared.
 * What might have caused this and how do I re-create this file?

 * It could be another plugin you are running that is deleting it. Are you running
   wp-spamshield? I know that plugin deletes the MU plugin from plugin organizer.

 * Hi Jeff and thanks for your quick reply.
 * No. I’m not using spamshield but my site is a large membership site (almost ready
   to go live) and there are many plugins (Beaver Themer, Beaver Builder, ACF, YellowPencil,
   Memberpress, AffiliateWP, SG Optimizer (with Javascript options off), Media Library
   Folders Pro, Codeboxer Bookmarks, Geo My WP, WP GeoIP Country Redirect, Advanced
   Forms Pro, BBPress, Yoast and a few others).
 * I’ll deactivate and delete ‘Plugin Organizer’ then reinstall and configure it
   again.
 * I now undertand how it works so it will be a lot cleaner and quicker for me now.
   While configuring it, I’ll keep my file manager open and check that the MU file
   isn’t deleted. I’ll also frequently check my previously slow admin and front-
   end pages to make sure they are still loading quickly.
 * So, if anything goes wrong I will see it immediately, know the likely cause and
   let you know.
