I did this: enabled the XML sitemap function (and, to test the problem, I've disabled all other plug-ins - it makes no difference so I've re-enabled them)
I expected the plugin to do this: create sitemap files that I could see.
Instead it did this: the XML sitemap tool says it has created sitemaps. I can feed the four filenames it lists into Google Webmaster Tools and it seems happy with them.
But I can't actually see the files using FileZilla. Another tool - Traffic Travis - says my site doesn't have a sitemap.
So I'm confused - is there a sitemap or isn't there?
