Blogger Error 550 - Permission Denied

I got the error message "Error 550 - Permission Denied" when I tried to update and republish this blog last to fix some problems with archived files. The error occurred with the atom.xml file, which is the last thing that is published if you republish your entire blog.

I found this was because the "Site Feed" settings had a directory path. This had somehow been set to a / character, where it should have been set to nothing at all to publish to the root directory of my site. Changing it to nothing at all fixed the problem.

I also found a post in Tim's Journal here that explained some other causes of this error.
