I have just purchased and started using it. I was able to generate the sitemap for my whole site using the free version (of course, only up to 500 pages), however, by using the paid version, only 1 page was indexed.
This are my settings:
1. Starting URL: [external links are visible to admins only]
2. Maximum pages = 0
3. Maximum Depth Level = 0
Please kindly advise if there is anything I missed out, thank you.
