Webdesk or SelfService 7.4
The history panel or sidebar in WebAccess cannot be expanded once it has been collapsed.
This was raised as Problem 5123, The issue is arising due to a setting that is put in the user preference profile of having the panel collapsed, which then prevents the panel from re-expanding. There is a workaround for this which is a SQL script. The script deletes the entry from the profile for all users but as this can occur again, it would advisable to run this as a stored procedure which then allows the user to expand the panel again.
SQL statement to reset pane below:
delete from tps_user_preference where tps_system_preference_guid = (select tps_guid from tps_system_preference where tps_name = 'IsHistoryVisible') ;
NOTE: In order for a row to be created in the tps_user_preference table, the user must have create privilege on Modules - System - Non-Process Related Object - User Preference. Without this privilege, the history panel should re-appear when the user's session has expired.
This problem was fixed in version 7.5
