#14475: Memcached plugin masks setting changes on multisite installs

     Type:  defect (bug)  |      Status:  new            
 Priority:  normal        |   Milestone:  Awaiting Review
Component:  Cache         |     Version:  3.0            
 Severity:  major         |    Keywords:  memcached      
 I'm using WP 3.0.1 in a multisite configuration with the Wordpress
 memcached plugin version 2.0.1 from svn trunk. memcached version is 1.4.5.
 I'm also using HyperDB to split reads and writes between remote master and
 local slave MySQL instances.

 When the memcached plugin is enabled, I am unable to effect changes within
 the administrative interface. I don't have an exhaustive list, but things
 I've noticed include editing user profiles, adding post categories,
 editing posts, etc. The changes make it to the database, but the new
 values are not displayed in the web interface.

 If I restart or flush memcached, I can see any changes I've made, but any
 new ones are masked. If I uninstall the plugin or shut down
 memcached, everything works fine.
