Hi! Have you applied the patch Chris mentioned earlier to me (it works for me on 2.4.1b1): ----- Original Message from Chris ----- The "right" fix for this is this diff: Index: SessioningInterfaces.py =================================================================== RCS file: /cvs-repository/Packages/Products/CoreSessionTracking/SessioningInteraces.py ,v retrieving revision 1.4 diff -r1.4 SessioningInterfaces.py 101d100 < id = 'session_id_mgr' In other words, just remove "id = 'session_id_manager'" from the SessionIdManagerInterface class. :-( I'll be putting out a new CST release shortly. [Ahem!! ;-)] ----- End Original Message from Chris ----- I guess Chris is using the patched version, yes? Cheers Joachim P.S.: Joachim: On the server I prepared for you, CST is up and running ;-)
