I have bought the Standalone XML Sitemap Generator and followed the Step-By-Step Installation Guide carefully, but when i finished the installation and started with my sitemap crawling at my [external links are visible to admins only]. It seem that it didn't work for me as when i Clicked the button "run" at the crawling tab, it went back to the Configuration tab. Moreover, i tried to make some changes at Configuration field and saved but it didn't save my changes, either.
Could anyone please help and let me know i may do something wrong.
Thank you in advance!
