UI Error

System

Hi. We are testing with our 6.7.1 install. We attempted to modify the UI (it wasn't me, so I'm not sure what specifically was done). Now the UI displays:

"An error occurred checking isAllowedOnContainer on command com.interwoven.ui.base.wizard.WizardCommand"

It also produces this when trying to tag content.

Any ideas as to where we should be looking?

TIA
