Hi: I searched but could not find anything current on this, so sorry if this is redundant.
Running WP 3.2.6. and getting the error message "The last build succeeded, but the file was deleted later or can't be accessed anymore. Did you move your blog to another server or domain?"
I had previously deleted the sitemap.xml and sitemap.xml.gz files as I was trying to correct an issue of having my WP site in a sub-directory, and found this tutorial (http://www.youtube.com/watch?v=LUZicWWQUUs) on how fix it (maybe I should have listened closer and copied the files over to the root, not deleted them) TIA for any help.
