There was a problem retrieving data for this field.

You are trying to edit user profiles, either from your profile page, or perhaps in the User Profiles service application in Central Administration. You notice that some of the profile properties have the rubric: "‚ÄčThere was a problem retrieving data for this field. Updating values in this field is disabled temporarily. You can still update values in other fields." Oh, well; at least some of the properties work. But it would be really peachy if we could get rid of those pesky red messages.

This problem occurs because some of the properties use the Managed Metadata Service Application to provide term sets. That means that these properties are dependent on the Managed Metadata Service being set up properly. There are a few reasons why this might not be the case:

You set up the User Profiles Service Application before setting up the Managed Metadata Service (or didn't realize you needed it). You set up Managed Metadata but it is not working for one of a variety of reasons (e.g. the service was not started before the service application was created). Managed Metadata is working okay but there is no connection in the proxy group. (Go to Central Administrator->Application Management->Manage Web Applications->Service Connections button on the ribbon).
