I've been using Arne Brachhold's SiteMap plugin for a few months, but recently, something happened, and it no longer was able to generate the sitemap file. I changed the file attributes from 664 to 666 and it was able to generate the file again, but I am concerned that 666 would be a security issue on the file. Is 666 O.K? If not, is there a way to get around this problem? Thanks for the help.
