Post, and page sitemaps work, but I am getting an error on the category sitemap. I've been reading about it on the Net, and it looks like the solution is to edit every single category one by one (I have over 200 websites with about 8 categories each).
Is there any way to get it to work without going to Posts -> Categories -> Edit?
PS. It actually works on one of my blogs (another site) and on this one it doesnt. Both run with W3 Total Cache.
