I've been trying to get my sitemap.xml setup for about a week now and for some reason I am not able to generate one. I've followed both these XF 1.4 - "no sitemap" error (XenForo 1.4) And, And still nothing is working. I've tried rebuilding caches and run the cron entries and I still hit the same problem After trying my idea, I have successfully got it working. I went back into my Xenforo zip (The one you download from xenforo.com/customers and I took and added the sitemap.php. Because the file didn't exist on my server, after successfully uploading the sitemap.php I navigated my way to Rebuild caches and rebuilt the sitemap one (Just as a precaution). I also did the same with cron entries. I then when back to the XML sitemap generator and saved changes. And, it worked!
