How to update site search after feed URL changes?

First, I should note that I’m just a Wonkette reader. I have no connection with their company or team.

Last weekend, Wonkette migrated from self-hosting to Substack. In the process their feed URL changed from to The former no longer exists.

When I try to add a feed and search for “wonkette”, the match that comes up has the old, broken feed URL. The actual site at seems to have the new feed info correctly available. How is the Newsblur search result updated to use the new feed URL?

right click a site in the left panel or drop down the menu at the top next to the feed’s name and pick site settings. paste the new address in the “Change RSS Feed Address” section and hit the parse button.
