When I accepted sample data on install I did not realize there would be 200 contacts added with no clear way to get rid of them. How do I delete these contacts?
The quickest way is to:
- Run a contribution search with no criteria. You will have a result page with all of them.
- For the Select Records option, choose All Records.
- For the Actions option, choose Delete Contributions.
- Repeat for contacts with Advanced Search; type "Sample Data" into the "Contact Source" field to find all sample contacts and then bulk delete them. This will cascade down to delete events, activities, etc. You'll also get a message that your own record can't be deleted, so there's no concern about wiping yourself out of the system.
First delete all test contributions following Nicholai's answer.
Then do an "Advanced Search" and type "Sample Data" into the "Contact Source" field. You can then select all results (should be exactly 200 of them) and bulk-delete them.
