I am currently working on EP 7.0. I am getting webdynpro pagebuilder expired error message while accessing nwa, system admin, content admin etc.
I have checked several threads on the same error and tried the following.
1]tcwddispwda set to 7200
2]Session.timeout set to -1
3]Jsession.cookiedomain set to NONE
4]Session expiration set to 16 hrs
5]Login ticket_lifetime set to 16 hrs (same as session expiration as per note 842635).
6]Checked for pb application in nwa (Could not find expiration parameter here)
7]Checked page timeout value 15000 ms
But all my attempts have failed. Please let me know what more options can be tried.
PS: https is configured for access to portal.
