Hello, I am using your generator on a mobile site [ External links are visible to forum administrators only ] which i have on a separate hosting account from the root domain due to needing a unique IP to install an SSL certificate on it. The sitemap is empty after running. I thought it may be the robots.txt file blocking it, which i change a day or so ago, but even your Google tool test works now.
There doesn't appear to be any errors in the debug log.
