Plugin Organizer is not set up correctly.

Hi Jeff.  I'm having a strange problem.  I'm in the process of moving a site from to  For some reason PO ver 9.4 can't read the version from the mu-plugin file.  I'm getting this error in the PO admin area:

You are running an old version of the MU Plugin. Please use the tool provided on the settings page to move the updated version into place or manually copy /var/www/vhosts/sitename/wp-content/plugins/plugin-organizer/lib/PluginOrganizerMU.class.php to /var/www/vhosts/sitename/wp-content/mu-plugins/PluginOrganizerMU.class.php.  If you don't do this the plugin will not work. This message will disappear when everything is correct.

I checked the wp-options table.  PO_version_num is 9.4.  The I don't think it's a file permissions issue on the mu-plugins folder or the files in it.

I've deactivated/deleted/reinstalled Plugin Organizer a few times.  Nothing seems to help.

Any idea what I might be running into?

The hosting environment is the same.  (Different server, but same O/S, PHP version, etc.)

Thanks for any insight you can provide.


Did you manually move the MU plugin file like the error says to do?
