I'm surprised you are getting this message at this point. I'm going to assume
that you were not editing the document in Editor. If you edit your document in
Editor, it won't let you make those invalid changes. It stops you at the time
you are trying to make the change.
The message indicates that you are attempting to change something in a position
that either does not allow a change tag or does not have change attributes. In
these cases, it is impossible for the application to track the change. What you
need to do in that situation is make the change in a different way. So, for
example, instead of changing content, you may need to delete the entire element
and re-insert it. Or, instead of deleting an entire table row, you may need to
only delete the content of each cell. There are ways to work around all of the
situations as you come to them.
If you can determine what the change is that it isn't allowing, maybe we can
give you some additional advice.
