# Multisite Activation Error

 * I run a **local **version of WordPress with **multisites**. When the plugin is
   activated it causes a sitewide error – “**Sorry, You Are Not Allowed to Access
   This Page**”. I have to delete the plugin to gain access to my site.
 * I am using the latest version of WP and the plugin.
 * When activated, WP debug comes up with:
 * _PHP Notice: Use of undefined constant AUTH\_COOKIE – assumed ‘AUTH\_COOKIE’ 
   in …\wp-includes\pluggable.php on line 769_
 * This error does not present when the plugin is deleted/deactivated.
 * Can anyone help me to get this plugin to work on my multisite installation?
 * Thanks,
    Sarah

 * I run two websites on a multisite instance using the plugin and have no issues.
   Are you using the most current version of wordPress and Rootspersona?

 * Hi Ed, thanks for your reply. Yes, I am using the most up to date versions of
   both WP and plugin (as per my first post).
 * I have noticed a few other posts here regarding multisite activation errors, 
   so I’m not alone. I activated it last year but wasn’t ready to use it so deactivated
   it, therefor I know it should work with the few plugins and theme I use. However,
   when activated it crashes the WP admin section rather than sites, so I don’t 
   think it’s a clash between plugins/theme but rather something with WP itself.
   I downloaded a fresh plugin to test against with the same results.
 * I’ve just now discovered that rather than “Network Activate”, if activated directly
   from the site I will be using it on it doesn’t caused WP to crash. This must 
   have been what I did last time. It still doesn’t solve the network activation
   issue, but at least I can now tinker around wit the plugin until I am ready to
   make my site live.

 * Now I remember why I decided not to use it. I’m running WP locally via XAMPP,
   but Apache crashes when uploading the GEDCOM and no matter what setting I change
   I can’t seem to get it to work. I will test it out on one of my live sites.
