Hello All-

I've been using the memcache session store sucessfully since rails 2.0, but after starting a new app with v 2.1 I'm getting the following error at each page request:

This is happening with both 2.1 and edge. Any pointers? Any updated howtos out there?

thanks Mike Kohout

FYI, my memcache settings started as this

development: memcache_options = {    :compression => false,    :debug => false,    :namespace => "app-dcru-#{RAILS_ENV}",    :readonly => false,    :urlencode => false } memcache_servers = [ 'localhost:11211' ]

config.action_controller.fragment_cache_store = :mem_cache_store, memcache_servers, memcache_options

cache_params = *([memcache_servers, memcache_options].flatten) CACHE = MemCache.new *cache_params ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.merge!({ 'cache' => CACHE }) config.action_controller.session_store = :mem_cache_store

then I whittled them down to this: config.action_controller.session_store = :mem_cache_store

neither work with >= rails 2.1

Hi, I have the same problem. try to comment these lines in your config/environment.rb: config.action_controller.session = {    :session_key => '_app_session',    :secret => 'a_long_hash_key' }

That's work for me ! And I used rails v 2.1
