2281150 - Users of the default groups get blank main page after migrating users and groups from BOMM 3.1 - Information Steward

• Upgraded/migrated BOMM 3.1 to Information Steward (IS) 4.2.
• Prior to migrating the BOMM 3.1 users/groups in the UML tool, it worked fine.
• After the migration, users of the default IS groups get blank main page while logon IS:
  
• The Administrators group doesn't get impacted (still works fine without the problem).
• The following error appears in the InformationSteward.Explorer.log when the issue happens:
