Cannot edit wiki pages-- Exception message: Invalid field name

Question

We have migrated from one Sharepoint 2010 environment to another Sharepoint 2010 environment and only wanted to preserve a few sites, mostly Enterprise Wiki Sites.
We have imported 5 total Enterprise Wiki Sites, all of which point to particular Term Sets in Managed Metadata. 
2 wikis are pointed to term set A, 2 wikis are pointed to term set B and one wiki is pointed to term set C.
One of the wikis pointed to term set A is working, and one is not
The malfunctioning wiki has the following symptom:
Whenever you try to edit a page (new or existing) and save your changes, regardless of whether it is tagged, you cannot save your changes.  When you try, you get the error below.
Error
Failed to get value of the "Wiki Categories" column from the "Managed Metadata" field type control. See details in log. Exception message: Invalid field name. {f863c21f-5fdb-4a91-bb0c-5ae889190dd8}

Go back to site
To me, it looks like there is an invalid URL, since it gives the URL path, and then there is a space, and then it also has a relative URL to /wiki/adminwiki/pages ...is this normal?
Any ideas on how to fix this is great.  I don't think it has anything to do with the Managed Metadata service or the Term Store since the other wiki site (pointing to the same exact Term Set) is working normally with no problems.

Answer 1

To solve the problem make sure that the template you are using for the current page (with errors) has the same content type as the page. In example of the Enterprise Wiki page, I forgot to set the content type to an Enterprise Wiki page on a custom page
template I just added to the Master pages.
So what I had to do is:
go to properties of the page with errors described above and set it to be
Enterprise Wiki page
go to master pages and set the custom template to be of the same type, Enterprise Wiki page
That solved the problem
