This error means that both of the constituents you are merging are registered for the same TeamRaiser event, and both of them have a URL shortcut for their personal page. So when the system tries to merge them and merge the TeamRaiser profiles, it can't because you can't have two different URL shortcuts for the same person. To resolve this, simply remove the URL shortcut for one of the records:
  1. Go to Fundraising > TeamRaiser
  2. Next to any TeamRaiser event click "Manage"
  3. Search for the name of the constituents. If you are merging two constituents with different names, you will want to do this in two separate tabs in your browser to compare.
  4. Examine the Event Name column in the results and identify any TeamRaiser(s) that both people are registered for. If you find multiple TeamRaisers that both constituents are registered for, you may need to perform the steps below multiple times. Select one of the participant records for the event by clicking on their name.
  5. Next to where it says "Personal Page" click "Edit"
  6. Scroll down to the very bottom and you will see the keyword for their URL shortcut underneath where it says "You can create a personalized Web address for your personal page..." Remove that shortcut and save for one of these constituents, and you should be able to merge without a problem.
  7. If you found multiple events that both constituents are registered for, repeat steps 5-6 for each event.
