I removed the login window and when I click on the log off buttom displays this error

Location : cls_ps_frame/CVPageSet::GetFieldListAttri
Message : Fieldset () does not exist in spec_fieldsets : PageSet Name = frame

Any ideas?

Since you already removed the login feature, you don't need to log off. Please remove the log off link so that no one accidentally click it.
