I was trying to fix a site which had moved (given the subscriber numbers, I’m not alone!) However, I could not change the site URL or the feed URL — both gave me a 404 error, despite the URLs being valid as best I can tell.
I posted a video of my attempt:

NewsBlur URL of the site is https://www.newsblur.com/site/790/sim….
