I use Constant Contact for email marketing. I have integrated constant contact to display in a contact view in the field, "Campaign History." It has been working for over a year. All of a sudden it is no longer displaying properly. I have attached an image of what visual force is now displaying the field. 



Error code from scrolling:
only whitespace content allowed before start tag and not E (position: START_DOCUMENT seen E... @1:1)
Error is in expression '{!FetchNextSummary}' in page ctct21:contactcampaignhistory: (CTCT21)

An unexpected error has occurred. Your solution provider has been notified. (CTCT21)

If you have an idea of what may be causing an error, that would be extremely helpful.
