Underlying Error message - where navigation is supposed to be

Went to login to make an update to our site and we have the error message (pasted below) where our navigation is supposed to be.  Can someone please advise how i am supposed to resolve this problem so that I can make updates to our site.  

Error Message:
Problem assembling output for item (name=“index.html”, id=169-101-10893) with template: perc.widget. Underlying error: Trying to find the get method for property region_overrides on a property that was not lazy loaded. See log for stack trace.

Hi Kristy,

We are going to bring this ticket into our support portal to further investigate as we’ll want to see some more details.
