It's pretty much what it says - Something is stored in the session
that Rails can't pull out because it can't find the corresponding
class. What have you been putting in the session (and as a general
rule it's good practice to keep to fairly simple data in the session
(arrays, hashes, strings, numbers etc.)

Well you need to figure out what those plugins are doing. If you
restart your browser and the problem goes away then the problem was
just that when the session was created one of these plugins was
putting stuff in it (although this does highlight the danger of
storing that kind of stuff in the session). If not then keep digging -
you should always understand what the plugins you use are doing!

Thanks Fred My problem is solved by clearing history of browser.
